3/4 inch CPVC Coupling Plastic x Plastic

3/4" CPVC Coupling – Engineered for Pressure Systems and Thermal Reliability

The 3/4" CPVC Coupling (P x P) is a precision-molded fitting designed for solvent-weld connections in chlorinated polyvinyl chloride (CPVC) pressure piping systems. Manufactured from durable CPVC material, this coupling ensures reliable performance in both hot and cold water distribution lines, particularly where corrosion resistance and thermal stability are critical.

Suitable for residential, commercial, and industrial applications, this fitting meets ASTM D2846 standards and is NSF certified for potable water use. Its slip-fit ends are designed to join two pieces of Schedule 40 CPVC pipe seamlessly, delivering consistent joint strength and long-term reliability under pressure and temperature variations.

Benefits of High-Performance CPVC Couplings

• ✅ Code-Compliant Design – Conforms to ASTM D2846 and CSA B137.6 standards for potable water distribution.
• ✅ Thermal Stability – Handles continuous service temperatures up to 180°F, ideal for hot water systems.
• ✅ Chemical Resistance – Withstands aggressive water conditions and chlorinated environments.
• ✅ High Pressure Rating – Supports up to 400 psi at lower temperatures per manufacturer specifications.
• ✅ Non-Metallic Construction – Immune to galvanic corrosion and scale buildup, extending system service life.

Installation Guidance

Ensure all pipe ends are square, chamfered, and thoroughly cleaned before joining. Use CPVC-compatible primer and solvent cement as per ASTM F402 and manufacturer guidelines. Allow proper cure times based on ambient conditions and pipe size prior to pressure testing. Pressure test according to code and project specifications.

Typical Use Cases

Commonly installed in residential and commercial water distribution systems, this coupling is ideal for straight-line pipe extensions or repairs requiring high strength and thermal resistance. Also suitable for mechanical rooms, branch lines, and vertical risers.

Did You Know?

CPVC systems offer superior performance over traditional metal systems in aggressive water environments, including areas with high chlorine content, contributing to longer service life and reduced maintenance.

The 3/4" CPVC Coupling is a trusted solution for professional-grade installations where consistent performance and code compliance are non-negotiable. Specify this coupling for your next project and ensure a secure, long-lasting connection across your CPVC network.
