2 inch CPVC Coupling CTS x CTS

2" CPVC CTS Coupling – High-Temperature Rated Socket Connector

The 2" CPVC CTS (Copper Tube Size) Coupling is designed for joining CPVC piping systems in residential, commercial, and industrial applications. Manufactured from chlorinated polyvinyl chloride (CPVC), this socket-style coupling offers excellent heat resistance and mechanical strength, making it suitable for hot and cold potable water distribution systems.

This component is molded to precise tolerances to ensure reliable solvent-weld connections. It complies with ASTM D2846 standards for CPVC hot and cold water systems and is certified to NSF/ANSI 61 and 14 for potable water use. The coupling’s pressure rating typically supports up to 100 PSI at 180°F in CPVC systems when installed per manufacturer guidelines.

Performance Features

• Material: CPVC Type IV, Grade 1 (cell classification 23447 per ASTM D1784)
• Nominal Size: 2 inches CTS
• Connection Type: Socket x Socket (solvent weld)
• Pressure Rating: 100 PSI @ 180°F (when used in compliant systems)
• Temperature Range: Up to 200°F intermittent

Applications

• • Domestic hot and cold water distribution
• • Hydronic heating systems (non-steam)
• • Commercial potable supply piping
• • Low-pressure chemical transport (consult chemical resistance chart)

Installation Notes

Install using solvent cement and primer specifically formulated for CPVC piping. Pipe ends should be chamfered and thoroughly cleaned to ensure full bonding surface contact. Allow adequate cure time per cement manufacturer’s specifications before pressure testing the system. Not for use with compressed air or gas applications.

Compliance and Certifications

• Standards: ASTM D2846, ASTM F438
• Certifications: NSF/ANSI 61, NSF/ANSI 14, CSA B137.6
• Lead-Free: Compliant with Reduction of Lead in Drinking Water Act

Engineered for long-term performance, this 2" CPVC coupling is a dependable component in systems requiring resistance to high temperatures, internal pressure, and corrosive conditions. Its consistent sizing and robust material characteristics make it a preferred choice for solvent-weld CPVC assemblies in potable water applications.
