Parker A6TU6-MG Union Tee Fitting 3/8 Inch Od 300 Psi

Product Description

The PARKER A6TU6-MG is a push-to-connect union tee tube fitting designed for tube-to-tube connections in pneumatic and fluid distribution systems. Constructed from acetal polyoxymethylene, this fitting handles up to 300 psi working pressure and operates across a temperature range of -20 degrees F to 180 degrees F. The tee configuration allows a single inline tube run to branch in three directions without additional adapters or tools. Plumbers, HVAC technicians, and fluid system installers use this fitting where quick, reliable connections are required without compression sleeves or threaded assembly.

This fitting is suited for light commercial and residential applications involving pneumatic controls, water distribution tubing, or instrument air lines. The push-to-connect design reduces installation time on new construction and retrofit jobs alike. Its tan acetal body resists common chemicals encountered in HVAC and plumbing environments. The 3/8 inch OD tube size is a standard dimension in many pneumatic and low-pressure fluid circuits.

Compatibility

Designed as an OEM-style push-to-connect replacement fitting for use with 3/8 inch OD tubing in pneumatic, instrument air, and low-pressure fluid distribution systems.

Installation Notes

Installation does not require special tools — tube ends should be cut squarely and deburred before insertion to ensure a proper seal. Shut off and depressurize the system fully before removing or installing any fittings. Verify that tubing material and wall thickness are compatible with push-to-connect retention before pressurizing. Follow applicable plumbing or pneumatic codes, including IPC guidelines where relevant, for pressure-rated tubing connections.
