Proline 6633-003 Push-on Tube Pipe End Cap, 1/2 In.

The ProLine 6633-003 Push-On Tube Pipe End Cap is a reusable fitting designed to seal the ends of 1/2 inch copper or CPVC tubing. This push-on cap installs without heat, glues, caulks or special plumbing tools, making it faster and easier than traditional soldered or glued joints. Simply push it onto compatible tubing and remove it later if access is needed—the same fitting reinstalls with equal ease, making it ideal for pressure testing, central heating systems, temporary connections and system modifications.

Push-on caps are ideal for applications where the flow of water needs to be interrupted. Unlike traditional connections, this removable fitting lets you service your plumbing system in direct or indirect cold water systems, unvented and vented hot water systems, and more without cutting and rewelding pipes.
