1-1/2 inch CPVC Coupling CTS x CTS

1-1/2" CPVC CTS Coupling – Engineered for Performance and Reliability

The 1-1/2" CPVC CTS Coupling is specifically designed for chlorinated polyvinyl chloride (CPVC) systems, offering consistent strength and chemical resistance for potable water and pressure piping applications. Its socket connections provide a solvent-welded joint that ensures a secure and long-lasting seal in both residential and commercial systems.

Manufactured to precise tolerances, this coupling facilitates a tight fit, helping reduce potential leak points while supporting system integrity under varying pressure and temperature conditions. Ideal for hot and cold water lines, it performs exceptionally in environments requiring long-term thermal resistance and corrosion protection.

Advantages for Professional Installations

• ✅ High-Temperature Capability – Rated for continuous service up to 180°F at 100 psi, suitable for hot water distribution lines.
• ✅ Corrosion and Chemical Resistance – Impervious to most household and industrial waterborne chemicals.
• ✅ Structural Integrity – Engineered from high-performance CPVC for long-term mechanical strength.
• ✅ Solvent Weld Joint – Socket end connection creates a fusion bond for permanent leak-free assembly.
• ✅ Uniform Wall Thickness – Promotes even flow and consistent pressure across the system.

Installation Considerations

This coupling is designed for solvent cement welding. For optimal performance, surfaces should be properly cleaned and primed before applying CPVC solvent cement. Always follow manufacturer guidelines and local code requirements when assembling fittings. Avoid overtightening or applying torsional force to the joint post-assembly.

Typical Applications

Commonly installed in CPVC potable water piping systems, including hot and cold domestic water lines in single-family and multi-family dwellings, commercial buildings, and institutional plumbing networks. It is also used in retrofit situations where corrosion resistance and thermal durability are required.

Note

CPVC fittings should not be used for compressed air or gas systems and should be protected from prolonged UV exposure in outdoor applications unless otherwise specified by the manufacturer.
