Watts 0651138 Push-to-connect Tube Fitting 1 in Od

Product Description

The WATTS 0651138 is a push-to-connect tube-to-tube fitting designed for fast, tool-free connections in plumbing and fluid-handling systems. Constructed from brass with an EPDM O-ring seal, it accepts tubing with a 1 inch outside diameter on both ends. The push-to-connect mechanism allows a technician to make a secure, leak-resistant joint without soldering, threading, or compression nuts. This fitting is suited for residential and light commercial plumbing applications where quick assembly and reliable sealing are priorities. It weighs 0.72 pounds and ships as a single unit.

This fitting is used in tube-to-tube connections where both sides of the joint share a 1 inch OD. Typical install scenarios include potable water supply lines, hydronic heating circuits, and general fluid distribution piping. The brass body handles the pressure and temperature demands common in residential plumbing systems. Plumbers and pipefitters working on new construction or retrofit jobs will find the push-to-connect design reduces labor time compared to soldered or threaded alternatives.

Installation Notes

Installation is performed by licensed plumbers or pipefitters. Shut off the water supply and depressurize the line before making or breaking any connection. Ensure tube ends are cut square, deburred, and clean before inserting into the fitting to achieve a proper seal. Verify that local plumbing codes and applicable IPC provisions permit push-to-connect fittings for the intended service application.
