3 inch PVC DWV Plug

3 inch PVC DWV Plug – Male Threaded Termination Fitting for Non-Pressurized Systems

The 3 inch PVC DWV Plug with Male Pipe Thread (MPT) is designed for use in gravity drainage systems requiring a secure and removable termination. Constructed from rigid polyvinyl chloride (PVC), this fitting provides a dependable seal at cleanouts, test points, or future connection locations in non-pressurized waste and vent piping networks.

This plug threads into a 3 inch female pipe thread (FPT) fitting and meets dimensional and material requirements for Schedule 40 DWV applications. Commonly installed in horizontal and vertical runs, it offers straightforward installation and reliable long-term sealing performance when used with approved thread sealing compounds or PTFE tape.

Key Features

• ✅ Male Threaded (MPT) Design – Enables a removable closure point in female-threaded DWV fittings.
• ✅ Schedule 40 PVC Construction – Lightweight, corrosion-resistant material suitable for indoor and underground drainage systems.
• ✅ 3 inch Nominal Size – Compatible with standard 3 inch DWV pipe and fittings in residential and commercial applications.
• ✅ Low-Pressure Rating – Intended for use in gravity-fed systems only; not rated for pressurized fluid systems.
• ✅ Code Compliant – Manufactured to ASTM D2665 and designed to meet IPC and UPC code requirements for DWV fittings.

Installation Guidelines

Apply thread sealant or PTFE tape to male threads prior to installation. Tighten by hand, then apply final torque using an appropriate wrench or square-drive fitting as specified by the product manufacturer. Over-tightening should be avoided to prevent thread distortion or cracking. Not for use in hot water or pressurized applications.

Common Applications

Typically used in sanitary drainage, waste, and vent systems for cleanouts, test ports, or to cap unused branches. Appropriate for both above-grade and buried configurations when installed in accordance with local code and manufacturer recommendations.

Standards & Compliance

Conforms to ASTM D2665 and CSA B181.2 standards for PVC DWV fittings. Approved for use in residential, commercial, and institutional construction under applicable plumbing codes.
