Fitment Guide

Professional-Grade Air Line Fittings for Heavy-Duty Performance
When you are hauling heavy payloads or towing a large 5th-wheel, the integrity of your air suspension is non-negotiable. The RETRUE Brass Air Line Fittings are designed to provide the ultimate mechanical connection for your air bags. Whether you are replacing a leaking plastic fitting or upgrading to a high-pressure system, our brass connectors deliver the durability that professional haulers demand.

Engineered for the American "Salt Belt" and Extreme Heat
Truck undercarriages face road salt, mud, and extreme heat. Unlike standard fittings, RETRUE’s Premium Brass construction won't become brittle or corrode over time. The DOT-certified 1/4" OD tubing compatibility ensures that your air brake lines stay connected even under the intense vibrations of off-road driving or highway cruising.

Perfect Fit for Ford, RAM, and GM Truck Puck Systems
Our fittings are precision-engineered to match standard 1/4" NPT or 1/8" NPT ports, making them compatible with almost all onboard air compressors, air tanks, and air spring bellows. The push-to-connect mechanism makes DIY repairs fast and easy, getting you back on the road in minutes instead of hours.
