Anvil FIG 7001 Gruvlok® Flexible Coupling w/Nitrile C Style Gasket, Ductile Iron Ptd. Orange

Flexible Grooved Coupling for High-Pressure Industrial Piping

The Anvil Gruvlok® FIG 7001 is a high-strength, flexible coupling designed for versatile grooved-end pipe connections across a broad range of industrial sectors, including mining, oil fields, and process piping. Engineered for durability without excessive weight, this ductile iron coupling supports working pressures up to 1,000 PSI.

This coupling's flexible design significantly reduces pipeline noise and vibration while simplifying equipment installation by accommodating minor misalignments and thermal expansion. It's equipped with a Grade "T" Nitrile C-style gasket which is ideal for petroleum-based services, mineral oils, and air containing oil vapors. It can also be used in data center immersion cooling applications with oil-based dielectric fluids, but other types of liquid cooling setups should use the version with an EPDM gasket instead.

Key features:

• Maximum Pressure: Up to 1,000 PSI (69 bar) (depends on coupling size)
• Temperature Range: -20°F to 180°F (-29°C to 82°C)
• Housing Material: ASTM A 536, Grade 65-45-12 ductile iron with rust-inhibiting orange paint coating and zinc-electroplated hardware
• Approvals: UL listed and FM approved for fire protection and industrial standards

NOT FOR USE IN HOT WATER OR HOT AIR.
