1/2 inch CPVC Union Slip x Copper Male

1/2 Inch CPVC Union – Slip x Copper Male Adapter

The 1/2 inch CPVC Union with Slip x Copper Male Adapter provides a transition between chlorinated polyvinyl chloride (CPVC) pipe and copper tubing systems. This union is engineered for systems that require serviceability and a dissimilar material connection, commonly found in potable water distribution applications.

Material and Connection Specifications

This union combines a solvent-weld CPVC socket end with a machined male copper adapter, allowing secure joining of CPVC piping to sweat copper fittings or tubing. It features a union nut for disassembly without cutting, facilitating maintenance and future modifications.

• ✅ Material: CPVC body with brass or copper male adapter insert
• ✅ Connection Type: 1/2 inch CPVC slip x 1/2 inch copper male
• ✅ Thread Standard: NPT male end conforms to ANSI/ASME B1.20.1
• ✅ Certifications: NSF/ANSI 61 and 372 for potable water systems; lead-free compliant

Typical Applications

This union is used in hot and cold water systems where CPVC and copper need to be joined without the use of dielectric unions. Common in retrofit situations and equipment hook-ups where future disconnection may be required, including residential supply lines, recirculation loops, and water heater connections.

Installation Guidelines

Install using CPVC solvent cement and primer on the socket side per ASTM F493. The copper male adapter may be threaded into a female fitting or connected to a sweat joint using appropriate flux and solder. Union nut should be hand-tightened and then snugged with a wrench. Do not overtighten.

• ✅ Sealant: Use PTFE tape or approved thread compound on male threads if threaded into metallic fittings
• ✅ Temperature Rating: Up to 180°F continuous use (dependent on system design)
• ✅ Pressure Rating: Typically up to 100 PSI at 180°F in potable water systems

Product Features

• ✅ Union Body: Allows pipe disassembly without cutting, ideal for service access
• ✅ Corrosion Resistance: CPVC is inert to chlorinated water and most household chemicals
• ✅ Material Transition: Effectively connects dissimilar piping materials in code-compliant configurations

The 1/2 inch CPVC Union Slip x Copper Male Adapter provides a practical solution for connecting CPVC piping to copper lines in potable water systems. Designed for systems requiring access or disassembly, this union ensures compatibility, durability, and leak-resistance across a range of residential and commercial plumbing applications.
