3/4 inch CPVC Cap

3/4 inch CTS CPVC Socket Cap – For Sealing Potable Water Lines with Confidence

The 3/4 inch CTS CPVC Socket Cap is engineered to securely seal off CPVC piping in residential and commercial water distribution systems. Manufactured from chlorinated polyvinyl chloride (CPVC), this cap is intended for use in hot and cold potable water systems, offering long-term performance under demanding conditions.

Its socket (slip) connection allows for solvent-weld installation on Copper Tube Size (CTS) CPVC pipe. The cap is pressure rated and temperature resistant, making it ideal for terminating unused branch lines or temporarily sealing sections during testing or phased installation.

Product Features

• Material: CPVC (Chlorinated Polyvinyl Chloride)
• Size: 3/4 inch CTS
• Connection: Socket (solvent weld)
• Maximum Working Pressure: 400 psi @ 73°F
• Temperature Range: Up to 200°F

Installation Guidelines

Install using a solvent cement welding process approved for CPVC materials. Ensure pipe ends are square-cut, cleaned, and properly primed if required by local code. Use only compatible CPVC solvent cement for a permanent bond. Allow appropriate cure time before pressurizing the system.

Applications

• Potable water supply termination points
• Isolating test segments during pressure testing
• Temporary capping during construction or remodeling phases
• End-of-line protection on hot and cold water distribution lines

Did You Know?

CPVC offers superior resistance to chlorine degradation and is approved for direct contact with drinking water. It also maintains structural integrity at higher temperatures compared to standard PVC, making it suitable for domestic hot water lines.

This 3/4 inch CTS CPVC socket cap delivers reliable sealing performance in systems where durability, compliance, and chemical resistance are critical. An essential component for contractors working with CPVC distribution systems.
