1/2 inch PEX Copper Insert Coupling PEX x CPVC

Ensure Precision Transitions with the 1/2 Inch PEX Copper Insert Coupling – PEX x CPVC

The 1/2 inch PEX Copper Insert Coupling provides a reliable connection solution for transitions between PEX and CPVC systems. Designed to meet rigorous installation demands, this coupling ensures mechanical integrity and long-term system compatibility in residential and light commercial water distribution lines.

Application-Specific Engineering

This insert coupling is engineered to accommodate systems where cross-material transitions are required, particularly in retrofits or expansions involving mixed piping systems. With precision-machined barbed and socket ends, it delivers a secure interface for press-fit and solvent weld applications.

• ✅ Dual Material Interface Supports a PEX connection on one end and a solvent-weld CPVC socket on the other, eliminating the need for extra transition components.
• ✅ Machined Copper Alloy Manufactured from lead-free brass or copper alloy, in compliance with NSF 61-G and national potable water mandates.
• ✅ System Compatibility Designed for use in ASTM F1807 or F2159 PEX systems and ASTM D2846 CPVC piping.

Installation Guidelines

Use with industry-standard crimp, clamp, or expansion PEX tools on the barbed end. The CPVC socket must be properly primed and solvent welded using an approved solvent cement. Ensure the piping is fully seated and allow for cure time per solvent cement manufacturer instructions before pressurization.

Specifications

• Nominal Size: 1/2 inch
• Connection Ends: PEX insert (barbed) x CPVC solvent weld socket
• Material: Lead-free brass or copper alloy compliant with ANSI/NSF 372
• Pressure Rating: 100 psi at 180°F for PEX systems
• Certifications: NSF 61, NSF 14, and ANSI/NSF 372 lead-free

Typical Applications

Commonly used during water line conversions, repipes, or new builds where legacy CPVC systems require integration with modern PEX tubing. Found in domestic hot and cold water systems, particularly in confined installations where compact transition fittings are necessary.

Code Compliance Reminder

All potable water fittings must meet current lead-free requirements. This coupling is certified for use in all 50 states and is suitable for installation per UPC and IPC plumbing codes.

For reliable transition performance between dissimilar piping systems, the 1/2 inch PEX Copper Insert Coupling delivers consistent results in accordance with national standards. Specify this fitting for efficient, compliant connections on your next project.
