Weatherproof. Trail-tested. Made for Extremes.

+Air Coupler is your air system’s first line of defense—engineered for exterior mounting and built to thrive in punishing conditions. From the scorching heat of Mexico to the deep freeze of Alaska, it’s been thoroughly tested through sandstorms, torrential rain, and winter blizzards.  

At its core is the proven Dixon 2UM3-B universal coupler, sealed inside a precision-molded TPU overmold that shields it from impact, grime, and the elements. Rain, salt, mud, or snow—+Air Coupler shrugs it all off.

Whether you're airing up tires, running tools, or making a trailside repair, it gives you fast, reliable access to your onboard air—without popping the hood or cracking a door.

Mount it where it makes the most sense for your build:

• Outside the vehicle using +Air Expansion.

• Integrated cleanly into Fusion Series Jeep mounts.

• Inside the cab with your SideKick seat-mount system.

Part of the Nomadyn ecosystem—designed to adapt to wherever your adventure takes you.  Made for extremes.
