AN10 PTFE hose finished with a nylon braided cover. AN10 is a volume size used for oil cooler feeds and returns, turbo oil drains, dry sump plumbing and large fuel supply circuits. The PTFE liner brings the usual advantages of zero fuel vapour permeation, full compatibility with ethanol and methanol blends and stability in hot oil. The nylon cover is the point of difference at this diameter: it is lighter than a stainless braid and easier to route, which matters when you are running a large hose across a chassis, and it will not saw into paint, looms or other hoses. Use hose ends designed for nylon-covered PTFE hose.
