1 inch CPVC Coupling Plastic x Plastic

1" CPVC Socket Coupling – For Pressure and Hot Water Distribution Systems

The 1" CPVC Coupling is a socket-style fitting used to join two sections of CPVC piping in pressurized hot and cold water systems. Manufactured from chlorinated polyvinyl chloride, this coupling is designed to meet the requirements of high-temperature, high-pressure fluid conveyance in both residential and commercial applications.

Engineered to industry standards, the coupling provides chemical resistance, dimensional stability, and consistent wall thickness, making it suitable for both potable water and light industrial fluid systems. Solvent welding is required to ensure a permanent, leak-resistant connection between pipe segments.

Key Performance Features

• ✅ CPVC Material Composition: Formulated for temperature service ratings up to 200°F (93°C) under pressure, depending on system design.
• ✅ Solvent Weld Socket Ends: Compatible with Schedule 40 and Schedule 80 CPVC piping systems.
• ✅ High-Thermal Stability: Maintains mechanical properties at elevated temperatures, enabling safe use in domestic hot water and hydronic systems.
• ✅ Non-Metallic Construction: Corrosion-resistant and suitable for systems where metal leaching or electrochemical reactions are a concern.
• ✅ Meets Industry Standards: Typically manufactured to comply with ASTM F439 or ASTM F441 for CPVC fittings.

Technical Specifications

• Material: CPVC, Type IV, Grade 1 per ASTM D1784
• Nominal Size: 1 inch
• Connection Type: Socket x Socket (solvent weld)
• Pressure Rating: Up to 100 psi @ 180°F (based on pipe schedule and installation)
• Certifications: Typically conforms to NSF 61 (potable water) and ASTM F441

Installation Considerations

Installation requires the use of CPVC-compatible primer and solvent cement per the manufacturer's instructions. Joint assembly must be completed while the solvent is still active. Allow appropriate cure time based on ambient temperature and pipe size before pressurizing the system. Ensure piping is cut square, deburred, and free from debris prior to solvent welding. Use in accordance with applicable plumbing code requirements.

Application Use Cases

This fitting is intended for use in hot and cold potable water systems, recirculating lines, industrial process water, and light chemical distribution networks. It is also suitable for use in CPVC fire sprinkler systems where approved. Commonly installed in risers, branch lines, and manifold tie-ins where thermal and chemical resistance is required.

Material Note

CPVC exhibits superior performance in environments where PVC is unsuitable due to temperature limitations. It should not be used for compressed air or gas applications, nor in systems subject to freezing conditions without proper protection.

The 1" CPVC Socket Coupling delivers consistent sealing performance, thermal resistance, and dimensional accuracy for use in pressure-rated piping systems across a range of residential and commercial applications.
