PTFE is the ultimate hose material. It has outstanding resistance to chemicals including alcohol fuels such as methanol, ethanol, E85 and leaded fuels such as race gas. It is also suitable for brake, transmission, clutch, power steering, and coolant. PTFE hose has ~zero~ permeation and will not emit vapors like rubber fuel hose, so it is safe to use in confined spaces such as a vehicle’s trunk or small garage.
All Radium Engineering PTFE hoses have been successfully tested in-house to 1200psi although PTFE can typically withstand 2500psi+. They are also for extreme temperatures (-94F to +480F). They feature an extruded PTFE (fluoropolymer) core wrapped in a stainless steel wire braided sleeve. The outer coating for the universal DIY ends is braided PET. All hose ends are type-II black anodized aluminum.
