Tough lightweight hose that is a sure bet for racers and performance enthusiasts. It's versatile, flexible, easy to cut and assemble with a number of attractive characteristics including: excellent temperature resistance -40 degree to +300 degree F, high tube strength, tight bend radius capable of tight engine compartments. 3-ply construction consists of full coverage Nylon-bonded outer braid for abrasion-resistance, partial coverage embedded braid middle layer, and CPE synthetic rubber inner tube for great flow and high temperature resistance. XR-31 Hose is made in the USA and offers a significant weight-savings over stainless steel braided hose. Because today's fuels can contain a wide variety of unpublished additives, it is not possible for us to accurately predict compatibility of the inner liner of XR-31 hose with any specific fuel. We recommend HS-79 Teflon-lined hose, if in doubt. XR-31 hose is NOT compatible with brake fluid. Shown with Black AN Hose adapter, which is not included. Temperature Range is -40°F to 300°F. See Specifications Tab for Max Pressures

XR-31 Nylon Braided Hose is Sold by the foot, i.e. add quantity 6 for 6ft. Of hose.

Hose comes in maximum of 25 feet sections. Please specify if you want sections cut into specific lengths when ordering over 25 feet.
