1 inch Copper Coupling with Stop Copper x Copper

1 inch Copper Coupling with Stop – Designed for Code-Compliant, Leak-Resistant Systems

The 1 inch Copper Coupling with Stop is a full-port, wrought copper fitting designed to connect two sections of copper tubing in plumbing systems requiring directional continuity without flow restriction. Manufactured in compliance with ASME B16.22 and certified lead-free under NSF/ANSI 61 and 372, it ensures mechanical strength and dimensional accuracy for long-term service in potable water, HVAC, and hydronic heating systems.

Its integrated stop feature ensures proper pipe alignment during soldering or brazing, preventing over-insertion and improving the consistency of joint depth across installations. This fitting is compatible with hard-drawn and annealed copper tube types K, L, and M and is suitable for both residential and commercial use.

Product Performance and Key Features

Applications

This coupling is used extensively in domestic water supply systems, hydronic distribution lines, and chilled or hot water applications. It provides reliable, straight-line transitions for pipe sections where full flow is required without directional change.

Installation Guidance

Prior to installation, both the fitting and tubing must be properly cleaned and deburred. Use of ASTM B813-compliant flux and lead-free solder is required for potable water systems. Apply uniform heat to achieve a continuous capillary bond. The stop feature assists with insertion depth, ensuring repeatable installations and reducing joint failure risk.

Regulatory Compliance

This product meets or exceeds performance and safety requirements under ASME B16.22, NSF/ANSI 61 & 372, and UPC/IPC plumbing codes. Its lead-free composition qualifies it for installation in systems requiring compliance with the Safe Drinking Water Act (SDWA).

Professionals depend on fittings that meet stringent tolerances and code standards. The 1 inch Copper Coupling with Stop offers a reliable solution for joining copper tubing with precision, durability, and compliance. Built for long-term service, it remains a standard component in commercial and residential copper piping systems.
