Series 368 Low-Permeation Marine Fuel Hose, Sold by the Foot

High-Performance Fuel Hose for Boaters: Shields Series 368 Low-Permeation Marine Fuel Hose

The Shields Series 368 is a USCG Type A1-15-certified, low-permeation marine fuel hose built for fuel feed applications aboard outboard-, inboard-, and inboard/outboard-powered pleasure boats. Where most hose installations demand tight bends through congested engine compartments, the Series 368 flexes into tight radius bends without collapsing or restricting fuel flow, making it the go-to choice for complex routing that other hoses can't handle without kinking. Polyester-reinforced construction with a plastic barrier veneer and Nitrile Butadiene Rubber (NBR) outer layer keeps fuel permeation to a minimum, satisfying both EPA and CARB very low permeation requirements. Compatible with gasoline (including up to 85% ethanol-blended fuels), diesel, and all biodiesel blends, this hose is rated for temperatures from -20°F to 221°F and handles a working pressure of 100 psi, with a burst strength of 250 psi. Suitable for above- and below-deck installations alike.

Surveyors routinely flag fuel lines that don't meet current standards, and the Series 368 is how you ensure that never becomes your problem. Certified to SAE J1527 Type A1-15 and ISO 7840 Type A1, and NMMA/CE type accepted, this hose checks every compliance box for new builds and repower projects. The weather and UV-resistant NBR/PVC outer cover holds up to the harsh conditions of the marine environment over the long haul. Sold by the foot in continuous lengths up to 50 feet, so you buy exactly what your installation requires without waste. Backed by a limited lifetime warranty and made in the USA.
