1-1/2 inch Copper Coupling less Stop Copper x Copper

1-1/2 inch Copper Slip Coupling – Wrot Copper C x C for Sweat Applications

The 1-1/2 inch Copper Slip Coupling is a straight repair fitting designed for joining two sections of copper tubing in non-threaded, soldered (sweat) applications. Manufactured from wrot copper, this coupling features a smooth interior with no internal stops, allowing for full insertion during repairs or extensions in copper supply lines.

Compliant with ASTM B75 and ASME B16.22 standards, this coupling is suitable for use in both residential and commercial potable water systems. The fitting is third-party certified as lead-free under NSF/ANSI 61 and NSF/ANSI 372 for safe use in systems delivering drinking water.

Key Product Features

• ✅ Connection Type: Copper x Copper (C x C) slip ends – solder joint required
• ✅ Material: Wrot Copper – ASTM B75 Type L or M compatible
• ✅ Size: 1-1/2 inch nominal
• ✅ Temperature/Pressure Rating: 200 psi at 150°F (per applicable copper tube ratings)
• ✅ Certifications: NSF/ANSI 61 and 372 lead-free compliant

Installation Guidelines

Prepare pipe ends by cleaning and deburring prior to applying flux. Insert pipe fully into the slip fitting and complete the joint using lead-free solder in accordance with local plumbing code. Heat should be evenly distributed for optimal capillary action. Because the fitting lacks a center stop, it is often used in repairs where standard couplings cannot be installed due to access or length constraints.

Common Applications

Typically used in hot and cold domestic water lines, hydronic heating loops, and other pressurized copper systems. The slip design makes it particularly useful in rework conditions or when replacing damaged segments in confined spaces where pipe cannot be moved axially.

Code Compliance and Material Use

All copper fittings for potable water use must be lead-free, defined by federal regulation as ≤0.25% weighted average lead content. This fitting meets that requirement and is approved for installation in jurisdictions enforcing the Safe Drinking Water Act (SDWA).

The 1-1/2 inch Copper Slip Coupling is a precision-machined component engineered for sweat joint connections in copper tubing systems requiring dimensional consistency and regulatory compliance. Properly installed, it delivers long service life and dependable sealing performance.
