Union- Tee 1/4in Tube x 1/4in Tube x 1/4in Tube

The Union Tee 1/4in Tube x 1/4in Tube x 1/4in Tube (SKU AIR21838) is a pneumatic fitting adapter designed for push-to-connect air line systems. This three-way tee connector branches a single 1/4-inch air line into multiple directions, making it essential for pneumatic suspension systems, air lift helper kits, and complex air distribution networks where multiple circuits require pressurized air from a central source.

The 1/4-inch female push-to-connect design on all three ports ensures rapid, tool-free assembly while maintaining reliable, leak-free connections. This standardized port configuration allows seamless integration with existing 1/4-inch pneumatic tubing and components commonly found in air suspension, air brake, and auxiliary air systems on trucks, trailers, and specialized vehicles. The compact dimensions (1.5 x 0.5 x 2 inches) and minimal weight (0.05 lbs) allow installation in space-constrained engine bays and under-chassis locations without adding significant system weight or bulk.

This tee fitting serves technicians and vehicle owners building or maintaining air lift helper kits, pneumatic suspension upgrades, and dual-circuit air systems. Whether consolidating air lines from a compressor to multiple airbags, creating bypass circuits, or distributing pressure across multiple solenoid valves, this adapter provides the junction point needed for proper air system architecture. The push-to-connect standard ensures field serviceability without specialized tools or crimping equipment.

Push-to-connect pneumatic fittings have become the industry standard for aftermarket air system installation because they eliminate the need for compression fittings, swaging, or braided line assembly—reducing installation time and potential leak points in the circuit. The 1/4-inch size handles the flow requirements of most light-to-medium duty pneumatic applications without excessive pressure drop across the fitting itself.
