Dura Plastics 450-002 Pvc Male Plug 1/4 Inch Mipt

Product Description

The DURA PLASTICS 450-002 is a 1/4-inch male iron pipe thread (MIPT) PVC plug used to close off open pipe ends in fluid-handling systems. Molded from PVC thermoplastic, this plug resists rust, scaling, and pitting under normal service conditions. It handles fluid service temperatures up to 140 degrees F, making it suitable for a broad range of plumbing, irrigation, and light industrial process applications. Licensed plumbers, HVAC technicians, and pool service professionals install this fitting as part of standard pipework closures and pressure-test setups.

This plug is commonly used in residential and light commercial plumbing systems, pool and spa equipment lines, irrigation manifolds, and chemical feed systems where corrosive fluids are present. The 1/4-inch MIPT thread mates directly with female-threaded ports on valves, manifolds, tees, and pipe fittings. Its PVC construction makes it appropriate for cold and warm water service, mild chemical lines, and applications where metal fittings would corrode or contaminate the fluid stream.

Key Features

• PVC thermoplastic construction resists rust, scaling, and pitting
• Rated for fluid service temperatures up to 140 degrees F
• 1/4-inch MIPT thread for direct engagement with female-threaded fittings
• Suitable for corrosive fluid applications where metal plugs are not appropriate
• Maintenance-free design for long service life in wet environments

Compatibility

Designed as a standard 1/4-inch MIPT PVC plug for use with any female-threaded PVC, CPVC, or compatible plastic pipe fitting or port accepting a 1/4-inch male pipe thread.

Installation Notes

A licensed plumber or qualified technician should install this plug following applicable IPC or local plumbing code requirements. Shut off system pressure and drain the line before threading in the plug. Apply thread sealant tape or compatible liquid thread sealant to the male threads before installation. Do not over-tighten PVC threaded fittings, as excess torque can crack the fitting body.
