3/4 inch PVC Schedule 40 Plug

3/4 inch PVC Threaded Plug – Schedule 40 Termination Fitting for DWV and Pressure Systems

The 3/4 inch PVC Plug is a Schedule 40 fitting used to terminate threaded ends in non-pressurized or low-pressure piping systems. Designed for use with standard 3/4 inch NPT female-threaded fittings or outlets, this plug ensures a mechanically secure seal that is resistant to chemical exposure and internal pressure in compliant installations.

Manufactured from Type I, Grade I PVC, this component conforms to ASTM D2466 and is NSF-certified for use in potable water systems. It is suitable for temporary or permanent sealing of unused outlets, test points, or system access ports in both residential and commercial construction environments.

Technical Specifications

• Nominal Size: 3/4 inch
• Fitting Type: Male Threaded Plug (MPT)
• Material: Polyvinyl Chloride (PVC), Cell Class 12454 per ASTM D1784
• Schedule: 40

Installation Notes

Apply PTFE tape or approved thread sealant to the male threads before insertion into the receiving fitting. Hand-tighten, then secure with a wrench, taking care not to overtighten and damage threads. Not suitable for use in systems subject to high vibration or pressure surges unless specifically rated. Always follow project specifications and local code for material compatibility and installation practices.

Typical Applications

Used to close off unused ports in valve bodies, tees, manifolds, or cleanouts. Commonly found in irrigation systems, potable water distribution lines, drainage systems, and chemical-resistant piping networks in both above-ground and protected outdoor applications.

Material Performance Insight

Schedule 40 PVC is widely used due to its favorable strength-to-weight ratio, resistance to corrosion and scaling, and compatibility with a wide range of fluids. The plug's compact design allows for clean termination in space-constrained installations or future-access provisions.
