Ndl Industries np-450-007 Pvc Pipe Plug 3/4 in Mnpt

Product Description

The NDL INDUSTRIES np-450-007 is a Schedule 40 PVC pipe plug with a 3/4-inch male NPT (MNPT) thread. It is used to cap or terminate threaded pipe ends in plumbing, irrigation, and industrial piping systems. The all-PVC construction resists corrosion and a broad range of chemicals, making it suitable for both residential and industrial service. Licensed plumbers and pipefitters install this type of fitting during system shutoffs, pressure testing, and line terminations. The smooth interior geometry keeps pressure drop to a minimum where flow is not the primary concern.

This plug fits standard 3/4-inch MNPT threaded female ports found in water supply lines, process piping, irrigation manifolds, and general-purpose fluid handling systems. Schedule 40 PVC fittings of this type are common in residential plumbing, light commercial installations, and low-pressure industrial applications where metal corrosion is a service concern. The MNPT thread allows the plug to thread directly into a female-threaded fitting, valve body, or pipe end without additional adapters.

Key Features

• Schedule 40 PVC construction for corrosion and chemical resistance
• 3/4-inch MNPT thread for direct installation into female-threaded ports
• Smooth inner walls reduce pressure drop in the line
• Suitable for residential and light industrial fluid handling applications
• Tested under cyclic pressure conditions for durability in demanding service

Compatibility

Designed as an OEM-style Schedule 40 PVC replacement plug for standard 3/4-inch MNPT female-threaded connections in residential and industrial piping systems.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off and depressurize the affected line before removing or installing any pipe plug. Apply a PTFE thread sealant tape or approved pipe thread compound to the MNPT threads before installation to ensure a leak-free seal. Do not overtighten PVC threaded fittings, as excess torque can crack the fitting body.
