CPVC Cap, 1/2 Slip

This American Granby CPVC cap in 1/2" slip size provides a clean, permanent way to close off the end of a 1/2-inch CPVC pipe run. CPVC is widely used in water-treatment and plumbing systems for its corrosion resistance and its ability to handle both hot and cold water, and a proper end cap is essential whenever you need to cap an unused outlet or terminate a line securely. It is the kind of small part that finishes a job properly rather than leaving a loose end behind.

• CPVC end cap from American Granby
• 1/2" slip (socket) connection
• Solvent-welds to 1/2" CPVC pipe for a permanent seal
• Corrosion-resistant CPVC material
• Suited to hot and cold water applications
• Very lightweight at about 0.01 lbs

The slip-fit socket is designed to be solvent-welded onto the pipe end with appropriate CPVC cement, creating a strong, leak-tight joint that effectively becomes part of the pipe itself. That makes the cap ideal for sealing off branch lines, capping future-expansion stubs you may want to extend later, or closing a section for pressure-testing during installation. It is one of those small fittings that turns out to be indispensable on nearly every CPVC project, and having a few on the truck saves a trip more often than you would expect.

A natural fit for treatment plumbing

Because CPVC resists the scaling and corrosion that can plague metal fittings, it pairs naturally with water softeners, filters, and other treatment equipment that runs continuously. A reliable end cap lets you finish those runs cleanly, whether you are terminating a manifold, isolating a leg of the system, or leaving room for a planned addition down the line. To install, deburr and clean the pipe end, apply primer and cement as directed, and seat the cap fully for a joint that lasts.

Keeping common fittings like this 1/2" cap on hand lets installers complete CPVC plumbing confidently without an extra trip to the supply house. Whether you are finishing a new system build or making a quick repair, this American Granby cap is a dependable way to close off a 1/2-inch CPVC line for good.
