4 in. Stainless Steel Braided Hose Assemblies w/ Male NPT Ends

Heavy-Duty 4-Inch Flexible Metal Hose for High-Capacity Fluid Systems

Designed for the intense demands of industrial infrastructure and large-scale data center liquid cooling, these 4-inch JME stainless steel braided hose assemblies offer a high-performance alternative to rigid piping. Each assembly features a T321 corrugated stainless steel inner core for flexibility and an outer stainless steel braid for pressure reinforcement. With a maximum working pressure of 260 psig and a burst pressure of 1,050 psig, these hoses are engineered to maintain integrity under significant stress while providing the vibration absorption necessary to protect sensitive pumps and chillers.

Equipped with Male NPT x Male NPT ends, these 4-inch hose assemblies ensure a secure, leak-resistant connection across a variety of cooling distribution units (CDUs) and industrial piping manifolds. They are particularly effective in high-density server environments where non-combustible materials and corrosion resistance to water-glycol mixtures are non-negotiable safety requirements.

• Vibration Mitigation: Requires a minimum live length of 12 inches to effectively dampen mechanical oscillations
• Precision Routing: Supports a static bend radius of 11 inches, ideal for navigating complex, tight-access installations
• Operational Durability: Stainless steel construction resists mechanical impact and environmental degradation much better than rubber or plastic
• Fire Safety: Non-combustible materials provide an added layer of protection in critical infrastructure where downtime is not an option
