ONAIR Straight Fittings
These are the same high-quality fittings we trust in every ONAIR build. Built from solid brass with pre-applied thread sealant, they deliver a clean, secure connection.

Each straight fitting is DOT-approved and designed for a precise push-to-connect airline fit, paired with an NPT-threaded end that seals instantly. Whether you're plumbing your struts, manifold, or tank, these fittings make the job easier and cleaner.
