Plastic & Composite Plugs

Plastic and composite plugs for pipe, tube and PEX: hex head plastic plugs, brass push-to-connect plugs, PEX plugs and MPT plugs. A plug closes a female port or an open tube end for testing, a capped branch or a line you plan to extend later. Match the plug to the port type and size, and to the system it goes into, because a PEX plug and a push-to-connect plug are not interchangeable. Each listing groups the stocked part numbers for one style. Choose size and thread on the product page.
