Proflex SS Braided Hose #10 x 20'

The Proflex SS Braided Hose #10 x 20' is engineered for serious automotive builders and mechanics who demand reliability in high-pressure fuel, oil, and coolant systems. This 20-foot braided hose serves as a critical component in custom engine builds, fuel injection conversions, and performance cooling upgrades where standard rubber hose cannot withstand pressure spikes or thermal cycling. Whether you're fabricating a street rod fuel system, upgrading a race engine's supply lines, or routing transmission cooler lines in a build, this hose delivers the durability that separates professional work from budget shortcuts.

Russell's stainless steel braiding provides both structural integrity and corrosion resistance, protecting the hose from salt spray, engine bay moisture, and fuel system solvents that degrade standard rubber over time. The #10 size (5/8-inch inner diameter) accommodates moderate to high fuel flow rates without restrictive pressure loss, making it ideal for carbureted, naturally aspirated, and moderately boosted applications. Braided construction flexes with vibration and thermal expansion while resisting abrasion from block edges and sharp chassis geometry, eliminating the pinhole leaks and splitting failures common in unbacked hose runs. The 20-foot length minimizes required coupling connections, reducing potential failure points in your fuel system.

Custom fabricators and performance shops specify Proflex braided hose for fuel injection retrofits, carb-to-pump feed lines, oil cooler circuits, and transmission fluid systems where pressure ratings exceed 100 psi. Installation requires JIC or AN-style fittings (sold separately) that crimp or screw onto the hose ends; verify your coupling specifications before ordering. This product works with virtually any fuel system configuration—EFI, carburetor, mechanical or electric pumps—provided fittings match your existing or planned system ports. The 5.31 lb weight is manageable for routing through engine bays or along frame rails without sagging between supports.
