1/2 inch CPVC Cap

1/2 inch CTS CPVC Cap – Chemically Resistant End Fitting for Hot and Cold Water Systems

The 1/2 inch CTS CPVC Cap is engineered to provide a permanent, solvent-welded seal at the end of a CPVC pipeline. Manufactured from chlorinated polyvinyl chloride (CPVC), this cap offers excellent resistance to corrosion, scaling, and chemical degradation, making it suitable for both residential and commercial plumbing systems handling domestic hot and cold water.

This cap is designed for use with copper tube size (CTS) CPVC piping and is commonly installed at the termination point of service lines or unused branches. The slip-style socket connection ensures a strong bond when installed using CPVC solvent cement and primer according to ASTM F493 guidelines.

Product Features

• Material: CPVC – rated for pressure-bearing hot and cold potable water lines
• Size: 1/2 inch CTS nominal
• End Type: Socket (Slip) x Closed End
• Temperature Rating: Suitable for continuous service up to 180°F (82°C)
• Pressure Rating: Rated to 100 psi at 180°F (per ASTM D2846)
• Standards: Conforms to ASTM D2846, NSF/ANSI 14 and 61 for potable water use

Installation Notes

Ensure pipe ends are cut square, deburred, and cleaned prior to joining. Apply approved CPVC primer and solvent cement per manufacturer instructions to both the pipe and fitting socket. Insert the pipe fully into the cap and hold for several seconds to allow bonding. Curing time varies depending on temperature and humidity.

Typical Applications

• Capping stub-outs during rough-in stages
• Isolating future branch connections
• Pressure testing segments during phased installation
• Temporarily or permanently sealing system ends

Key Advantages

• Corrosion- and scale-resistant internal surface
• Non-reactive with chlorine and chloramines in municipal water
• Suitable for installation in concealed spaces
• Compatible with SDR 11 CPVC pipe systems

Did You Know?

CPVC maintains higher impact strength and temperature tolerance than standard PVC, making it the material of choice for hot water distribution in residential and commercial plumbing systems.

When installed correctly, the 1/2 inch CTS CPVC Cap offers long-term performance and reliability in pressurized water distribution systems. Ideal for use in accordance with IPC and UPC plumbing codes where CPVC piping is permitted.
