Sch 40 PVC Plugs

Schedule 40 PVC plugs are pipe closure fittings used to seal and terminate open ends in PVC piping systems. Whether you're capping an unused outlet on a tee, closing off an irrigation zone, pressure testing a line before backfill, or terminating a cold water system, a PVC plug provides a reliable, watertight closure.

We stock the complete range of Schedule 40 PVC plugs in two connection styles — spigot (slip) and male threaded (MIPT) — in sizes from 3/8" through 12", with fabricated options available for large-diameter applications. Threaded plugs screw into place for a tight seal without adhesive, making them simple to install, replace, or remove when you need flexibility to change or expand the system later. Spigot plugs install into the socket end of an existing fitting using PVC primer and solvent cement for a permanent, watertight bond.

Standard plugs (excluding Class 125) meet ASTM D-1784, ASTM D-2466/2467, NSF/ANSI 14 & 61 — certified for potable water applications. Max operating temperature 140°F; pressure rating varies by size.
