Westlake Pipe Fittings P1146 Pvc Threaded Countersunk Plug 6in

Product Description

The WESTLAKE PIPE FITTINGS P1146 is a 6-inch PVC threaded countersunk plug designed to close off the end of a threaded pipe or fitting. Constructed entirely of PVC, this plug resists corrosion and chemical degradation common in plumbing and drainage applications. The countersunk design allows the plug to seat flush or below the surrounding surface, making it suitable for installations where a low-profile termination is required. Licensed plumbers and pipe fitters typically install this fitting in pressure or gravity-drain systems where a clean, secure pipe closure is needed.

This plug is used in residential and commercial plumbing systems where 6-inch threaded pipe ends must be capped or temporarily plugged. Its threaded connection ensures a secure, leak-resistant seal without the need for adhesive. Common applications include cleanout closures, pressure-test plugs, and end caps in PVC drain, waste, and vent piping systems. The countersunk head profile keeps the installed fitting from protruding beyond the pipe end, which is useful in tight or finished spaces.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off water supply and relieve system pressure before removing or installing any pipe plug. Hand-tighten the threaded plug first, then use a strap wrench or appropriate spud wrench to bring it to a snug fit - do not overtighten PVC threads, as this can crack the fitting. Verify no leaks after restoring system pressure.
