HPS Performance Products FKM-9F-032-BLUE FKM Silicone Hose 5/16" ID 9 Ft Blue Oil Resistant

The HPS Performance FKM-9F-032-BLUE is a high-temperature, oil-resistant silicone hose built for demanding underhood applications. FKM (fluoroelastomer) lined, this hose solves a common problem: standard silicone hoses degrade when exposed to fuel, oil, and other aggressive automotive fluids. The fluoroelastomer inner liner creates a barrier that minimizes fluid permeation, evaporation, and hose degradation, delivering performance that plain silicone simply cannot match.

Featuring 1-ply polyester reinforcement and a UV- and ozone-resistant outer jacket, this hose is engineered to hold up in harsh engine bay environments. It ships as a 9-foot length with a 5/16" (8mm) inside diameter, providing plenty of material for custom routing and trimming to fit.
