Dura Plastic 450-030 Pvc Male Adapter 3 Inch Sch 40

Product Description

The DURA PLASTIC 450-030 is a Schedule 40 PVC male adapter designed for threaded pipe connections in plumbing, irrigation, and industrial piping systems. With a 3-inch nominal size and male NPT (MNPT) end style, this fitting transitions between solvent-weld PVC pipe and female-threaded fittings or valves. It is a domestic-made fitting, suited for licensed plumbers and pipefitters working on pressure-rated PVC systems. The Schedule 40 wall thickness meets standard pressure ratings for cold water service and typical low-pressure industrial applications.

This adapter is commonly used in residential and commercial plumbing, pool and spa piping, irrigation distribution, and industrial process lines where a solvent-weld-to-threaded transition is required. The 3-inch nominal size serves main distribution lines and larger branch connections. Installers use this fitting when connecting PVC pipe runs to threaded valves, pumps, or equipment inlets.

• Male NPT end style transitions solvent-weld PVC to female-threaded connections
• Schedule 40 PVC construction rated for standard pressure service

Compatibility

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following IPC and local plumbing code requirements. Shut off and depressurize the system completely before cutting into any existing piping. Apply an approved PVC primer and solvent cement to the socket end per the cement manufacturer's instructions and allow full cure time before pressurizing. Use thread sealant tape or compound rated for PVC on the male NPT threads when mating to female-threaded fittings.
