These chemically resistant PTFE braided hoses are a necessity when dealing with harsh chemicals or solvents and high pressure applications. They provide a uniquely rugged, durable, and chemically resistant combination of Stainless Steel and PTFE by having an inner core of PTFE and protecting that with a braided stainless steel outer sleeve. These hoses have female JIC swivel on each end and they DO NOT require Teflon tape to create a seal. ***Note: Do not exceed the specified hose bend radius or the inner PTFE liner will kink and the hose integrity will become compromised and should not be used.
