Green Leaf F 3800 P 3/8 Inch Polypropylene Pipe Plug Mipt

Product Description

The GREEN LEAF F 3800 P is a 3/8 inch polypropylene pipe plug with male iron pipe thread (MIPT) end connections. Molded from black polypropylene, it provides a lightweight, corrosion-resistant seal for open pipe ends in plumbing, irrigation, and fluid handling systems. The F 3800 P carries NSF 61 and NSF 372 certifications, making it suitable for use in potable water applications where lead-free compliance is required. Plumbers and pipefitters install this type of fitting to cap unused branch openings, test lines, or temporarily close off supply ports during system work.

This plug is suited for residential and light commercial plumbing installations, irrigation manifolds, water treatment systems, and chemical distribution lines where polypropylene's resistance to corrosion and many common chemicals is an advantage. The MIPT thread pattern allows it to thread directly into female-threaded pipe fittings, valves, and manifold ports sized at 3/8 inch. It is a practical solution for capping low-pressure water lines, drain ports, and test taps.

Key Features

• 3/8 inch MIPT thread for direct installation into female-threaded fittings
• Polypropylene construction resists corrosion, moisture, and many common chemicals
• NSF 61 certified for contact with potable water systems
• NSF 372 certified for lead-free compliance
• Black color finish for easy visual identification
• Lightweight at under 0.01 pounds per unit

Compatibility

Designed as a standard 3/8 inch MIPT pipe plug compatible with female-threaded fittings, valves, and manifold bodies in potable water, irrigation, and fluid handling piping systems.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters. Shut off the water supply and relieve system pressure before threading the plug into any live line. Apply thread sealant tape or compatible pipe dope to the MIPT threads prior to installation to ensure a leak-free seal. Hand-tighten first, then snug with a wrench, taking care not to over-torque polypropylene fittings, as the material can crack under excessive force.
