Fitment

This is a universal air fitting or accessory. Match thread size and type to your system.

How to Choose

  • Match the threads: Check NPT size and gender before ordering.
  • Seal it: Use thread sealant or tape on NPT threads.
  • Plan the reach: Hose extensions help reach all four tires.
  • Ask us: We can help match fittings to your setup.

Why Run Onboard Air

Lower tire pressure gives you more grip in sand, rocks and mud, and a smoother ride. With onboard air you can air down at the trailhead and air back up before the drive home, without hunting for a gas station. You can also fix a slow leak on the trail and run air tools.

How to Install

  1. Release all air pressure.
  2. Apply thread sealant to the male threads.
  3. Thread and snug the fitting or hose.
  4. Pressurize and check for leaks with soapy water.

If you’re not comfortable with 12V wiring, have a qualified installer do it.

Care Tips

  • Check the intake filter often, especially in dust.
  • Inspect air lines and fittings for leaks.
  • Keep electrical connections clean and tight.
