Let's break down the differences.

Hard wall hose

Hard wall hose is the most durable option of the three. Built for demanding applications, it offers superior strength, excellent longevity, and outstanding resistance to ozone cracking and everyday wear.

Because of its rugged construction, hard wall hoses are ideal for high-use fueling environments where durability and reliability are essential. It is also UL Listed, meaning it meets recognized safety and performance standards for fueling applications.

Best For:

• Commercial fueling stations
• Heavy-duty industrial applications
• High-traffic fueling locations
• Customers looking for maximum service life

Soft wall hose

Soft wall hose is designed with a 4-spiral construction, making it lighter and more flexible than hard wall hose. This added flexibility makes it easier to handle, especially in applications where mobility is important.

While it is not as strong or abrasion resistant as hard wall hose, it still provides excellent performance for many fueling applications. Like hard wall hose, soft wall hose is also UL Listed.

Best For:

• General fueling applications
• Situations where flexibility is important
• Users looking for easier handling without sacrificing quality

Farm hose

Farm Hose is designed for agricultural, construction, and industrial applications where UL approval is not required. It features a 2-ply construction with a static wire, providing dependable fuel transfer at an economical price.

Although it is not as rugged as hard wall or as flexible as soft wall, farm hose is a practical solution for many off-road fueling needs.

Best For:

• Farms and agricultural equipment
• Construction sites
• Industrial fuel transfer
• Non-UL-required applications

Side-by-Side Comparison

Which Hose Is Right for You?

The right hose depends on how and where you'll be using it.

• Choose hard wall if you need maximum durability, long service life, and superior resistance to harsh conditions.
• Choose soft wall if flexibility and easier handling are your top priorities while still requiring a UL Listed hose.
• Choose farm hose for agricultural, construction, or industrial applications where UL approval isn't necessary and a cost-effective solution is preferred.

Using the wrong thread type can prevent a proper connection, cause delays, and create unnecessary frustration. Understanding the difference between NST (National Standard Thread) and NPSH (National Pipe Straight Hose) threads can help you choose the correct fittings and avoid compatibility issues.

What Are NST (NH) Fire Hydrant Threads?

NST (National Standard Thread), also known as NH (National Hose), is a common thread standard used for fire hose and fire hydrant connections in the United States. 

NST threads are commonly used for fire service applications, including:

• Fire hoses
• Fire department connections (FDCs)
• Fire hose nozzles
• Fire hydrants
• Fire apparatus

While many hydrants use NST threads, not every hydrant does. Thread standards can vary by city, county, municipality, and water system, so always verify the thread specification before purchasing a hose, fitting, or adapter. 

What Are NPSH Threads?

NPSH (National Pipe Straight Hose) threads are straight threads commonly used for industrial, commercial, pump, and water-transfer hose applications.

You'll often find NPSH threads on:

• Pumps
• Industrial hose assemblies
• Water transfer equipment
• Agricultural equipment
• General-purpose water systems

Although NST and NPSH threads may appear very similar, they are not designed to mate together reliably. Even if the thread size looks correct, differences in thread dimensions can prevent a proper seal or secure connection.

What's the Difference Between NST and NPSH Threads?

Because the differences are subtle, it's easy to mistake one for the other. Never assume two fittings are compatible simply because they thread together partway.

How to Identify Fire Hydrant Threads?

There are several ways to identify your hydrant's thread type:

1. Check with Your Local Fire Department or Municipality

The easiest and most accurate method is to contact the organization responsible for the hydrant. Many municipalities maintain records showing the exact thread standard used throughout their water system.

2. Measure the Threads

If records aren't available, you can measure the hydrant outlet using:

• A caliper to determine the outside diameter
• A thread pitch gauge to measure threads per inch

These measurements can then be compared with standard thread specifications to identify the thread type.

3. Use a Thread Identification Gauge

Thread gauges are designed specifically to identify fire hydrant and hose threads. They provide a fast and reliable way to determine compatibility before ordering fittings or adapters.

4. Look for Manufacturer Information

Some hydrants include identification plates or markings that list the manufacturer and model. With that information, the manufacturer can often confirm the original thread specifications.

What if my Equipment Has a Different Thread?

If your equipment uses a different thread standard than your hydrant, you'll typically need a thread adapter designed to connect the two thread types. 

Selecting the correct adapter requires knowing both:

• The hydrant thread specification
• The thread specification of your hose or equipment

When in doubt, consult your equipment supplier before ordering.

Why Thread Identification Matters

Using the correct thread type helps ensure:

• Secure, leak-free connections
• Faster equipment setup
• Improved safety during operation
• Reduced equipment damage
• Compatibility between hydrants, hoses, and accessories

Taking a few minutes to verify your hydrant's threads can save significant time and prevent costly mistakes in the field.

What Is a Prepay Nozzle?

A prepay nozzle is designed for fueling systems that require authorization before fuel can be dispensed. They are commonly used at retail fueling stations and other payment-controlled fueling systems. 

This added layer of control helps prevent accidental spills. If the nozzle's hold-open clip were to fail or remain engaged, fuel will not continue flowing because the system must first receive authorization to dispense fuel. Once the authorized amount has been dispensed or the fueling session ends, the system must be reset before fueling can resume.

Benefits of a Prepay Nozzle

• Requires authorization before fuel can be dispensed
• Helps control fuel-dispensing at payment-controlled stations
• Commonly used at retail and commercial fueling sites
• Helps prevent unauthorized or unintended fuel dispensing

What Is an Automatic Shutoff Nozzle?

An automatic shutoff nozzle is designed to automatically stop the flow of fuel once the vehicle or tank reaches its fill level. Inside the nozzle is a sensing mechanism that detects when fuel reaches the end of the filler neck, automatically shutting off the flow to help prevent overfilling.

Unlike a prepay nozzle, an automatic shutoff nozzle does not require the fueling system to be reauthorized after each fueling session. Its primary function is to automatically stop dispensing fuel when the tank is full.

Benefits of an Automatic Shutoff Nozzle

• Automatically stops fueling when the tank is full.
• Helps prevent overfilling and fuel waste.
• Simple and convenient for everyday fueling.
• Commonly used in fleet, agricultural, industrial, and commercial fueling applications.

Which Nozzle Is Right for Your Application?

The best choice depends on how and where you dispense fuel.

A prepay nozzle is ideal for fueling systems that require authorization before dispensing fuel, such as retail gas stations or other payment-controlled fueling applications.

An automatic shutoff nozzle is a great option for applications where the goal is to safely fill a tank without overfilling, making it a popular choice for fleet fueling, farms, construction sites, and commercial operations.

JME supplies a full range of aviation fueling equipment, and every hose assembly we build undergoes rigorous testing before it leaves our facility. Here's what goes into aviation fuel, how aircraft are fueled, and why hose testing matters so much. 

Understanding Aviation Fuel

Aviation fuel is a highly refined petroleum-based fuel specifically designed to power aircraft. Unlike fuels used for automobiles or heating systems, aviation fuel is manufactured to much stricter quality standards. It is often blended with additives that help prevent icing, improve performance, and reduce the risk of ignition under extreme operating conditions.

There are several primary types of aviation fuel, each designed for specific engine types.

Avgas

Aviation gasoline (Avgas) is used in spark-ignited piston engines, including reciprocating and Wankel engines. Various grades of Avgas are available, and many are dyed different colors to help identify the correct fuel type.

Jet Fuel

Jet fuel is a straw-colored fuel like diesel and is used in turbine-powered aircraft. It is the most common fuel used in commercial aviation and military aircraft. Military applications also utilize several specialized jet fuel variations depending on operational requirements.

Biofuels

Sustainable aviation fuels (SAF), biodiesel blends, and other biomass-derived fuels continue to gain popularity as the aviation industry works toward reducing emissions while maintaining high performance standards.

CNG & LNG

Although less common, some aviation applications utilize compressed natural gas (CNG) or liquefied natural gas (LNG) as alternative fuel sources.

How Aircraft Are Fueled

Most aviation fuel arrives at airports through underground pipeline systems before being stored in bulk fuel tanks. From there, fuel is transferred into refueling trucks or distributed through permanent fueling systems located throughout the airport.

Depending on the aircraft, fueling is typically completed using one of two methods.

Overwing Fueling

Smaller aircraft, helicopters, and piston-engine airplanes are typically fueled using the overwing method. Like fueling a vehicle, the fuel cap is opened, and fuel is dispensed through a conventional fueling nozzle into the aircraft's fuel tank.

Underwing (Single-Point) Fueling

Larger commercial and military aircraft commonly use underwing fueling, also known as pressure fueling or single-point refueling. This method connects directly to the aircraft's fueling system, allowing fuel to be transferred quickly and efficiently under pressure.

Selecting the correct fueling nozzle and equipment for each aircraft is essential for safe operation.

Aircraft Bonding & Grounding During Fueling

Aircraft naturally build up static electricity while flying. If that electrical charge is not safely dissipated before fueling begins, it could create a spark capable of igniting fuel vapors.

Before fueling:

• Aircraft should be electrically bonded to fuel equipment.
• Bonding connections should remain in place until fueling is complete.
• Some fueling operations also require grounding of the aircraft and fuel truck.
• Underwing pressure fueling systems utilize dead man switches to prevent unattended operation.

These safety procedures significantly reduce the risk of fire during fueling operations.

Why Aviation Hose Testing Is So Important

Aircraft refueling hoses operate under demanding conditions and must perform flawlessly every time they are used. That's why every hose should undergo rigorous hydrostatic testing before being placed into service.

Although many industrial hoses follow the NAHAD recommendation of testing at 1.5 times the working pressure, aviation fueling hoses follow the stricter API specification.

For example:

• Working pressure: 300 psi
• NAHAD test pressure: 450 psi (1.5× working pressure)
• API test pressure: 600 psi (2× working pressure)

Testing at the higher pressure provides additional confidence that the hose assembly can safely perform in demanding aviation fueling environments.

Inside the Aviation Hose Testing Process

At JME, aviation hose assemblies undergo a thorough inspection and hydrostatic pressure test before they leave our facility.

Step 1: Mark the Hose

Before testing begins, both ends of the hose are marked where the ferrule meets the hose. These marks confirm that the ferrule does not shift during testing, since any movement could indicate an improper crimp.

Step 2: Fill the Hose

Using a Rice Hydrostatic Test Pump, the hose is filled with water. Before pressure is applied, the hose is "burped" to remove any trapped air bubbles. Eliminating air ensures more accurate pressure testing while reducing stored energy during the test.

Step 3: Hydrostatic Pressure Test

The Rice Hydro is then used to gradually increase pressure until the hose reaches 600 psi, which is twice the hose's 300 psi working pressure in accordance with the API specification. The hose remains at this pressure for 10 minutes.

During this time, we carefully inspect the entire assembly for:

• Leaks
• Pinholes
• Bubbling
• Damage to the hose cover
• Any movement between the ferrule and hose

If the reference marks remain aligned after testing, it confirms that the crimp held securely throughout the pressure test, which indicates a good crimp.

Step 4: Drain the Hose

Once testing is complete, the pressure is safely released, and the water is drained from the hose.

Step 5: Perform an Ohms Test

The final step is an Ohms test.

Because aviation fueling hoses are designed to safely dissipate static electricity, verifying electrical continuity is critical. The Ohms test confirms that the hose assembly can properly conduct static electricity from one end of the hose to the other, helping reduce the risk of static discharge during fueling.

There are several different fuel nozzles available, all designed for different applications. There are some things to know when picking out your fuel nozzle, since they are designed for different flow rates, products, and materials.

Compatibility is one reason why it’s important to understand what you’re fueling. If you use the wrong nozzle, it can cause damage or contamination. Gasoline, diesel, DEF, chemicals, and oils all require different nozzles.

Flow rate and safety are two other reasons why it’s important. High flow diesel applications often need larger nozzles rather than gasoline and DEF systems. With safety, certain fuels require nozzles that are designed to reduce spills, static buildup, or accidental misfuelling.

Another reason why it’s important to understand what you’re fueling is because there are regulations that some industries have that have specific requirements for fueling equipment and nozzle types. Product purity requires dedicated equipment to prevent contamination that could damage vehicle emission systems, one example of this is DEF.

Understanding Nozzles

There are some things you need to ask yourself before choosing which nozzle is best for you. First, know what product you’re transferring. The most common fluids are:

• Diesel (UL or NON UL)
• Gasoline (Unleaded)
• Diesel Exhaust Fluid (DEF)

Second, know how the nozzle will be used. Will it be pressure activated, like at a gas station or convenience store using submersible pumps or dispensers? Or will it be used in a traditional fleet-fueling application, which is non-pressure activated?

One example is the Piusi DEF nozzle. It features an automatic shut-off, a hold-open clip, and a rack. It also contains special seal materials, meaning it is designed specifically for DEF and should not be used with other fluids.

The most common style of nozzle is the C-store application nozzle. When choosing one, ask yourself:

• What product am I transferring?
• What size do I need?
• What regulations or requirements apply?

Common Fuel Nozzle Sizes and Applications

The most common nozzle sizes used at gas stations are 1 inch and 3/4 inches, and in many cases, you can visually inspect the system to determine the correct size.

For 1-inch nozzles, OPW offers the 7H series, including the 7HB and 7H models.

• The 7HB is pressure activated and typically used at gas stations.
• The 7H is non-pressure activated and commonly used with Fill-Rite pumps in fleet-fueling applications.

Both models feature automatic shut-off and are available with or without a hold-open clip.

For 3/4-inch nozzles, OPW offers the 11 series, including the 11B and 11BP.

• The 11BP is pressure activated for gas station use.
• The 11B is non-pressure activated and designed for fleet-fueling applications.

There are also traditional fleet-fueling nozzles that keep things simple. These use a basic mechanical on/off design with no hold-open clip, although they can still hook onto equipment when not in use.

More advanced versions are also available with automatic shut-off, hold-open clips, and compatibility with nozzle docks.
