Green Leaf Rm 3438 P Reducer Nipple 3/4 X 3/8 in Mipt

Product Description

The GREEN LEAF RM 3438 P is a polypropylene reducer nipple designed to transition between 3/4-inch and 3/8-inch threaded pipe connections. It features male iron pipe thread (MIPT) on both ends, making it a straightforward threaded fitting for reducing pipe diameter within a plumbing or fluid-handling system. Constructed from black polypropylene, this fitting resists corrosion and is suited for water service applications. It carries NSF 61 and NSF 372 certifications, confirming compliance with drinking water safety and low-lead content standards. Plumbers and pipefitters install this fitting where a direct male-to-male threaded reduction is needed without additional adapters.

This reducer nipple is appropriate for residential and light commercial plumbing systems where a 3/4-inch to 3/8-inch pipe size reduction is required at a threaded connection point. Its MIPT x MIPT configuration allows it to thread directly into female-threaded fittings or valves on both ends. The polypropylene construction makes it a practical choice for cold and ambient-temperature water distribution lines, irrigation supply connections, and similar fluid-handling assemblies where a corrosion-resistant, lightweight fitting is preferred.

Compatibility

Designed as an OEM-style replacement or new-installation reducer nipple for threaded plumbing systems requiring a 3/4-inch to 3/8-inch MIPT x MIPT polypropylene fitting.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and relieve system pressure before threading this fitting into place. Apply an appropriate thread sealant tape or compound to the male threads before assembly to ensure a leak-free connection. Do not overtighten polypropylene fittings, as excessive torque can crack the fitting body.
