Pro-1 Fuel Line Hose 7/16 in ID x 5 ft – USA Made NRB/PVCC SAE30R6

Pro-1: A versatile low-pressure fuel line hose for everyday tasks

Manufactured in the USA by Pro-1, this 5-foot fuel line hose has a 7/16 inch inside diameter. It’s designed for non-injection fuel line work, providing reliable handling of common fuels at low pressures. It is not intended for fuel-injection systems, and its maximum working pressure is 50 psi, offering a practical limit for many workshop tasks.

Designed for flexibility and durability, the hose uses a nitrile tube with two spiral polyester reinforcements and a PVC/nitrile blend cover. This construction balances pliancy with strength, helping the hose resist kinks while remaining easy to route through tight spaces in engines or equipment bays.
