AN3 PTFE hose with a stainless steel braid over the liner, offered here as the longer-run listing for jobs that need more than a short off-cut. AN3 is the small-bore size used for brake and clutch circuits, oil pressure gauge and sender feeds and other lines where firmness matters more than volume. The PTFE liner does not swell, soften or weep the way rubber does, and it stays chemically stable against brake fluid, oils and alcohol-blended fuels, while the stainless braid keeps the hose from ballooning under pressure so pedal feel and gauge response stay sharp. Use AN3 PTFE hose ends designed for PTFE, not rubber-hose ends.
