Watts 0959290 Push-to-connect Union 1/2x3/4 Mght

Product Description

The WATTS 0959290 is a push-to-connect union tube fitting designed to create quick, tool-free connections between tubing runs in plumbing and fluid distribution systems. Constructed from polyethersulfone (PSU), this fitting handles up to 200 psi and accepts a 1/2-inch tube OD on one end with a 3/4-inch Male Garden Hose Thread (MGHT) connection on the opposite end. EPDM O-rings provide a reliable, leak-resistant seal. Licensed plumbers and pipefitters install this fitting in applications where fast reconnection or service access is required without soldering or compression tooling.

This fitting is suited for residential and light commercial plumbing installations where CTS (Copper Tube Size) tubing is in use. The push-to-connect design eliminates the need for solder, clamps, or specialized crimp tools, making it a practical choice for retrofit work, repairs, and tight-access installations. It is also appropriate for potable water supply lines, irrigation connections, and appliance supply applications where the MGHT thread configuration is needed at one port.

Compatibility

Designed as an OEM-style push-to-connect union fitting for CTS plumbing applications requiring a 1/2-inch tube OD to 3/4-inch MGHT transition connection.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters. Shut off the water supply and depressurize the line before making or breaking any connections. Ensure tubing ends are cut cleanly and squarely with a tubing cutter and are free of burrs before inserting into the push-to-connect port. Verify that all local plumbing codes and IPC requirements are met for the intended application before installation.
