Parker A8TU8-MG Push-to-connect Union Tee 1/2 Inch Od

Product Description

The PARKER A8TU8-MG is a push-to-connect union tee tube fitting designed for tube-to-tube connections in fluid and pneumatic plumbing systems. Constructed from polyoxymethylene (POM), this fitting accepts 1/2-inch outside diameter tubing on all three ports and is rated to 250 psi. The push-to-connect mechanism allows fast, tool-free tube insertion, reducing assembly time in tight spaces or high-volume installation work. Its tan-colored POM body offers good chemical resistance and dimensional stability across a range of temperatures. Plumbers, HVAC technicians, and industrial maintenance trades install these fittings where a reliable, inline tee connection is needed without soldering, threading, or compression tooling.

This fitting is suited for residential and light commercial plumbing, pneumatic control lines, and fluid distribution systems where 1/2-inch OD tubing is specified. Typical applications include instrument air lines, water distribution manifolds, and HVAC condensate or refrigerant-side ancillary tubing runs. The union tee configuration connects three tube runs in a single body, making it practical for branch-line installations where flow needs to be split or joined at a single point.

Key Features

• Push-to-connect design allows tool-free tube insertion and removal
• Union tee body joins three 1/2-inch OD tube lines in one fitting
• Rated to 250 psi for use in pressurized fluid and pneumatic systems
• Polyoxymethylene (POM) construction provides chemical resistance and dimensional stability
• Tan color for easy visual identification in multi-fitting assemblies
• Compact, lightweight design at 0.06 pounds

Compatibility

Designed for use with 1/2-inch outside diameter tubing in push-to-connect plumbing and pneumatic systems. Compatible with tubing types commonly used in fluid distribution and instrument air applications where POM push-fit fittings are specified.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC and pneumatic system technicians. Depressurize and drain the system completely before removing or installing any fitting. Ensure tubing ends are cut square and deburred before insertion to achieve a proper seal. Verify that system pressure and fluid compatibility are within the rated limits of the fitting before returning the system to service.
