AN4 PTFE hose with a stainless steel braid, supplied per foot. AN4 is the small-bore size that suits turbo oil supply lines, oil pressure sender and gauge plumbing, clutch circuits and low-demand fuel branches. The PTFE liner tolerates the heat of a turbo oil feed far better than rubber, does not harden or crack with age, and is unaffected by ethanol and methanol blends. The stainless braid resists abrasion where the line runs near hot or moving parts and stops the hose expanding under pressure. Note that PTFE hose has a minimum bend radius and does not like being kinked, so plan gentle routing and use PTFE-specific AN4 hose ends.
