Watts 0650771 Push-to-connect End Stop 1 Inch Od

Product Description

The WATTS 0650771 is a push-to-connect end stop tube fitting designed to terminate a tubing run without the need for tools or solvents. Constructed from polyphenylsulfone (PSU) in white, this fitting accepts tubing with a 1 inch outside diameter and is rated to 250 psi. The internal grab ring and integral seal create a secure, leak-resistant closure on open tube ends. Plumbers, pipefitters, and mechanical contractors install this type of fitting in potable water, compressed air, and fluid distribution systems where a clean, reliable tube termination is required.

This end stop is suited for residential and light commercial plumbing and fluid handling applications. It is particularly useful in situations where a branch line must be capped off temporarily or permanently, or where tubing layout requires a dead-end termination point. The push-to-connect design reduces labor time compared to threaded or solvent-weld terminations and does not require additional fittings, adhesives, or crimping tools on the job site.

Key Features

• Push-to-connect design installs without tools, solvents, or crimping equipment
• Rated to 250 psi for reliable performance in pressurized systems
• Polyphenylsulfone (PSU) construction offers chemical and heat resistance
• Accepts 1 inch OD tubing for a secure, leak-resistant termination
• White finish for easy identification in multi-line installations

Compatibility

Designed as an OEM-style push-to-connect end stop for use with tubing measuring 1 inch outside diameter in plumbing and fluid distribution systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and IPC requirements. Shut off and depressurize the system completely before inserting or removing the fitting. Ensure the tube end is cut squarely, deburred, and free of debris before pushing it fully into the fitting body to achieve a proper seal. Use the fitting manufacturer's release collar or a disconnect tool to remove the tube without damaging the grab ring.
