The VALUE COLLECTION 6631-005 is a push-to-connect tube-to-tube fitting made from lead-free brass, designed for joining copper or compatible tubing in plumbing and fluid-handling systems. It accepts tubing with a 1 inch outside diameter and is rated for a maximum working pressure of 200 psi. The EPDM O-ring provides a reliable seal across a broad range of temperatures and fluid types. This fitting installs without soldering or threading, making it a practical choice for licensed plumbers and service technicians working on repairs or new installations where quick, secure connections are required.
This fitting is suited for residential and light commercial plumbing applications where tube-to-tube connections are needed. It is commonly used in water supply lines, hydronic systems, and general fluid distribution where lead-free materials are required by code. The push-to-connect design reduces installation time and does not require open flame or specialized crimping tools, making it well-suited for tight spaces and service work.
Designed as an OEM-style replacement or new-installation fitting for tube-to-tube connections using 1 inch outside diameter tubing in plumbing and fluid-handling systems.
Installation is performed by licensed plumbers or qualified service technicians. Shut off the water supply and relieve system pressure before beginning work. Ensure the tubing end is cut cleanly and squarely and is free of burrs before inserting into the fitting. Verify that installation complies with applicable local plumbing codes and lead-free material requirements.
