HPS Performance Products FKM-9F-075-BLK FKM Lined Silicone Hose 3/4" ID 9 Feet Black Oil Resistant High Temp

The HPS Performance FKM-9F-075-BLK is a 9-foot length of 3/4" (19mm) inside diameter FKM-lined, high-temperature reinforced silicone hose in black. Engineered with an inner fluoroelastomer (FKM) liner bonded to a 1-ply polyester-reinforced silicone outer shell, this hose is purpose-built to handle fluids that would quickly degrade standard silicone hose — including gasoline, diesel fuel, automotive oils, and synthetic hydraulic fluids.

The FKM liner minimizes fluid permeation, evaporation, and hose degradation over time, while the polyester reinforcement layer delivers excellent flexibility and tensile strength. The result is a hose equally at home in high-performance automotive, marine, industrial, and motorsport applications.
