Watts 0651156 Push-to-connect End Stop 1/2 Inch Od

Product Description

The WATTS 0651156 is a push-to-connect end stop tube fitting designed to terminate or cap off a tubing run without the need for tools or solder. Constructed from brass with an EPDM O-ring seal, it accepts 1/2 inch OD tubing and creates a secure, leak-resistant closure. The push-to-connect mechanism allows the tube to seat and lock in a single motion, making it well suited for fast repairs, system modifications, or new installations where speed and reliability are priorities. Plumbers and pipefitters are the primary installers of this type of fitting.

This end stop fitting is used to cap an open tube end in residential and light commercial plumbing and fluid distribution systems. Typical applications include potable water lines, hydronic distribution loops, and similar low-pressure tubing systems where a clean tube termination is required. It is compatible with 1/2 inch OD tubing and is appropriate for use wherever push-to-connect fittings are permitted by local plumbing code.

Installation Notes

Ensure the tube end is cut cleanly and squarely and is free of burrs before inserting into the fitting to achieve a proper seal. Follow all applicable local plumbing codes, including IPC and IFGC requirements, for push-to-connect fitting use in your jurisdiction.
