1/4" DOT Air Brake Line Tee Fittings 2-Pack, 1/4" Tube OD x 1/4" NPT Thread Push-to-Connect Union, PTC/PTCR Composite Brass Fittings for Truck Air Suspension, Trailer Air Brake System
Complete Kit & Broad Compatibility: This set includes 2 pieces of 1/4" Tube Outer Diameter (OD) to 1/4" Side NPT Thread Tee Unions. Engineered with a PTC (Push-to-Connect) and PTCR (Threaded) composite design, they are fully compatible with SAE J844 Type A or B nylon tubing, making them an ideal choice for truck, trailer, and heavy-duty vehicle air brake systems
Effortless Push-to-Connect Installation: Our quick-connect technology simplifies assembly. Achieve a secure connection by simply pushing the tube into the fitting until it bottoms out; a light pull confirms it's locked. For disassembly, press the release ring and pull the tube out—no tools required, significantly speeding up maintenance and repairs

Superior Durability & On-Install Flexibility: Constructed from a robust brass and engineering-grade polymer composite, these fittings offer excellent corrosion resistance and reliable performance in low temperatures, extending service life and reducing maintenance costs. The fitting body can rotate 360 degrees after installation, allowing for precise tubing alignment in tight spaces and minimizing stress on connections
Wide Application & Rigorous Testing: Designed to withstand extreme temperatures from -40°F to +200°F (-40°C to +93.3°C) and operating pressures up to 250 PSI (17.2 bar). Ideal for truck air brakes, cab controls, air suspension, trailer slide rails, tire inflation systems, and pneumatic circuits in mobile machinery. Every fitting is factory-tested to guarantee performance and reliability
