ONAIR Union Fitting
$8.04

High-quality fittings that we use in every ONAIR build.

Our Union Fitting is built from solid brass and engineered for a clean, leak-free connection when joining two air lines together. Perfect for extending a line, fixing a cut, or cleaning up routing during your install.

Each union uses a precise push-to-connect design that locks the airline securely in place with a tight, reliable seal. No tools, no hassle — just push, click, and you’re set.

✅ Trusted by ONAIR installers
✅ Ideal for line extensions, repairs, and routing
✅ DOT-approved construction
✅ Choose your airline size above

Tip: Always ensure both ends of your airline are cut perfectly straight before inserting them into the fitting. For best results, use the ONAIR Airline Cutter for clean, accurate cuts every time.
