DESCRIPTION

[INDUSTRIAL-GRADE BRASS CONSTRUCTION] Engineered for maximum durability. Unlike plastic fittings that crack under pressure, our Air Line Tee Unions are made of solid brass, providing superior resistance to corrosion, wear, and high-impact vibrations in heavy-duty truck environments.

[PRECISION LEAK-PROOF SEALING] Say goodbye to air leaks and sagging suspensions. These fittings feature a high-precision internal locking mechanism that ensures an airtight, secure connection. Simply push the tubing in for a reliable seal that prevents accidental deflation or PSI loss.

[EXTREME TEMPERATURE RESILIENCE] Built to survive the American outdoors. Our air line fittings operate flawlessly in a wide temperature range from -4°F to 176°F (-20°C to 80°C). Whether you’re driving through a desert summer or a freezing northern winter, your air bags will remain fully functional.

[UNIVERSAL PNEUMATIC APPLICATIONS] Versatile and multi-purpose. This tee union is the perfect solution for inflating air bags, repairing truck and RV air lines, or connecting pneumatic tools and PVC pipes. Compatible with most standard 1/4" OD air line systems.

[REINFORCED PACKAGING & WARRANTY] We protect your gear. Every fitting is meticulously inspected and shipped in sturdy cardboard packaging to ensure it arrives in mint condition. Backed by a 120-day warranty and 24/7 dedicated support for a risk-free purchase.

Fitment Guide

Reliable Air Line Solutions for the Heavy-Duty Hauler
When you’re towing a heavy trailer or a high-end RV, your air suspension system is under constant stress. A single faulty fitting can lead to dangerous sagging and poor handling. The RETRUE Brass Air Line Tee Union is designed to provide the mechanical strength and airtight reliability required for professional-grade towing and suspension maintenance.

Engineered for Easy DIY Installation
We understand that truck owners value their time. Our push-to-connect technology eliminates the need for specialized crimping tools or messy sealants. The 1/4" tee union allows for a clean, professional-looking install when splitting air lines for balanced air bag distribution or adding a manual inflation valve.

All-Weather Durability for the Road Ahead
From the humid coastal air to salted winter highways, your truck's undercarriage takes a beating. By choosing premium brass over plastic, you are investing in a fitting that won't become brittle over time. This is the essential upgrade for owners of Air Lift, Firestone, or custom air-ride systems who demand "set-and-forget" performance.
