Parker A8UC5-MG Push-to-connect Union Fitting

Product Description

The PARKER A8UC5-MG is a push-to-connect union tube fitting designed for tube-to-tube connections in pneumatic and fluid handling systems. Manufactured from polyoxymethylene (POM), a high-strength acetal resin, this fitting accepts tubes with outside diameters of 1/2 inch and 5/16 inch and is rated for service up to 250 psi. The push-to-connect mechanism allows fast, tool-free tube insertion, reducing assembly time on plumbing, pneumatic, and light fluid distribution lines. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this fitting wherever a reliable, leak-resistant union connection is needed between two tube runs of differing or equal OD.

This fitting is suited for residential and light commercial applications where push-to-connect tube unions are required. Common install scenarios include compressed air distribution, water supply tubing, and instrumentation lines. The POM construction resists moisture and many common chemicals, making it appropriate for both wet and dry service environments. The tan color aids visual identification on the line. This part is sold and packaged individually.

Key Features

• Push-to-connect design allows tool-free tube insertion and fast field assembly

Compatibility

Designed as an OEM-style push-to-connect replacement union fitting for pneumatic, water, and light fluid distribution tubing systems using 1/2 inch and 5/16 inch OD tube.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance technicians. Before servicing or replacing any fitting, depressurize the line completely and verify pressure has reached zero before tube removal. Ensure tube ends are cut cleanly and squarely with no burrs or debris, as contaminated tube ends can compromise the push-to-connect seal. Verify the application pressure does not exceed the 250 psi rating of this fitting.
