About this part

Product Details

Vibrant Performance is known for making solid parts for custom fuel and fluid systems. These -8AN PTFE hose olive inserts are a perfect example of that focus. If you're working on a custom fuel line or any other setup using -8AN PTFE-lined hose, these little inserts are what you need to ensure a reliable connection.

What these do is simple but important: they go inside the end of your PTFE hose before you attach your hose end fitting. The insert keeps the soft PTFE liner from collapsing or getting pushed out of the fitting when you tighten it down. They're made from 6061 aluminum, which is strong enough to do the job without adding a lot of weight. Using these helps you get a leak-proof seal every time you put together a hose assembly, and they let you reuse your existing hose end fittings.
