Green Leaf M 1400 P Polypropylene Hex Nipple 1/4 in Mipt

Product Description

The GREEN LEAF M 1400 P is a 1/4 inch polypropylene hex nipple with male iron pipe thread (MIPT) connections on both ends. This black plastic fitting is designed for low-pressure piping applications where corrosion resistance and chemical compatibility are priorities. Made from polypropylene, it resists a wide range of fluids and mild chemicals without corroding or degrading. NSF 61 and NSF 372 certifications make it suitable for potable water system applications. Plumbers and pipefitters use this fitting to extend or connect threaded pipe runs in residential and light commercial installations.

This hex nipple is suited for residential and light commercial plumbing systems using 1/4 inch threaded pipe. Its MIPT x MIPT configuration allows it to thread directly into female-threaded fittings, valves, or equipment ports. The hex body geometry provides wrench flats for clean, controlled installation without slipping. Black polypropylene construction is appropriate for water supply lines, chemical distribution, and irrigation system connections where metal fittings would be prone to corrosion or galvanic reaction.

Key Features

• 1/4 inch fitting size with MIPT x MIPT end connections for direct threaded assembly

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4 inch MIPT threaded piping systems in residential and light commercial plumbing, water treatment, and irrigation applications.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and relieve system pressure before disassembling any threaded connections. Apply thread sealant tape or paste rated for plastic fittings to the male threads before assembly. Tighten with a wrench to the hex flats only — do not over-torque polypropylene threads, as cracking can result.
