Green Leaf F 3400P 3/4 Inch Polypropylene Pipe Plug Mipt

Product Description

The GREEN LEAF F 3400P is a 3/4 inch polypropylene pipe plug designed to seal threaded pipe openings in plumbing and fluid-handling systems. Constructed from black polypropylene, this plug resists corrosion and chemical exposure common in water distribution and light industrial piping. The male iron pipe thread (MIPT) end connection threads directly into a female-threaded fitting or pipe end to cap off unused ports or isolate system sections. It carries NSF 61 and NSF 372 certifications, making it suitable for use in potable water systems where lead content and material safety compliance are required by code.

This plug is used in residential and light commercial plumbing applications where a threaded port needs to be capped or a system branch needs to be closed off. Typical installs include capping unused tee outlets, test ports, or service connections in water supply lines. The polypropylene construction suits cold and moderate-temperature water service. Plumbers and pipefitters select this fitting when a lightweight, corrosion-resistant plug is preferred over metal alternatives in non-high-pressure, non-high-heat environments.

Key Features

• 3/4 inch MIPT end connection threads into standard female pipe fittings
• Polypropylene construction resists corrosion and common water treatment chemicals
• NSF 61 certified for use in potable water systems
• NSF 372 certified for low-lead compliance
• Black color provides UV resistance for exposed or partially exposed installations

Compatibility

Designed as an OEM-style replacement or standard-use fitting for 3/4 inch female-threaded pipe connections in residential and commercial plumbing systems.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters. Shut off water supply and depressurize the line before threading in the plug. Apply thread sealant tape or pipe dope to the male threads per local plumbing code requirements. Do not overtighten polypropylene fittings, as the material can crack under excessive torque.
