The GREEN LEAF RM 12116 P is a polypropylene reducer nipple designed to connect pipes of two different diameters within a fluid-handling system. It measures 1/2 inch by 11/16 inch and features male iron pipe thread (MIPT) connections on both ends, allowing it to thread directly into fittings or valves on each side. Molded from black polypropylene, this fitting delivers solid chemical resistance and lightweight construction suited for low-pressure plumbing, irrigation, and industrial fluid systems. Plumbers, pipefitters, and irrigation technicians are the primary installers of this type of fitting.
This reducer nipple is suited for residential and light commercial plumbing applications where a threaded pipe transition between two different pipe sizes is required. Common installations include irrigation manifolds, water treatment assemblies, chemical distribution lines, and HVAC condensate systems. The polypropylene material makes it appropriate for use with many water-based and mildly corrosive fluid systems. It is sold individually but carries a minimum order quantity of 5 units, making it practical for stocking in service vehicles or supply rooms.
Designed as an OEM-style threaded reducer fitting for use in standard MIPT-threaded polypropylene or compatible pipe systems requiring a 1/2 inch to 11/16 inch diameter reduction.
This fitting should be installed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes. Shut off and depressurize the line before removal of any existing fitting or installation of this nipple. Apply an appropriate thread sealant tape or compound rated for polypropylene and the fluid being carried. Do not overtighten, as polypropylene threads can crack under excessive torque.
