Green Leaf Rb 10-12 P Reducer Bushing 1x0.5 in Mipt Fipt

Product Description

The GREEN LEAF RB 10-12 P is a polypropylene reducer bushing designed to transition between a 1-inch male iron pipe thread (MIPT) inlet and a 1/2-inch female iron pipe thread (FIPT) outlet. Made from black polypropylene, this fitting reduces pipe diameter within a threaded piping system without the need for additional adapters. Its lightweight construction and corrosion-resistant material make it well suited for potable water, chemical distribution, and irrigation applications. The RB 10-12 P carries NSF 61 and NSF 372 certifications, confirming compliance with drinking water safety and low-lead content standards. Licensed plumbers and pipe fitters are the primary installers of this fitting in both residential and light commercial settings.

This reducer bushing is used wherever a threaded piping system must step down from a 1-inch line to a 1/2-inch branch or outlet. Common applications include potable water distribution, agricultural irrigation headers, and chemical-handling systems where metal fittings are undesirable due to corrosion concerns. The polypropylene construction handles a range of fluid types and resists scale buildup. Its MIPT x FIPT configuration allows it to thread directly into a female socket on one end and accept a male-threaded pipe or fitting on the other, making installation straightforward in both new construction and retrofit work.

Key Features

• Lightweight at 0.027 pounds per piece

Compatibility

Designed as an OEM-style threaded reducer bushing for use in standard 1-inch to 1/2-inch MIPT x FIPT threaded piping systems handling potable water, irrigation, or compatible fluid service.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the supply line before removing any existing fitting or installing this bushing. Apply thread sealant tape or pipe dope rated for polypropylene fittings to the male threads before assembly. Hand-tighten first, then use a strap wrench to avoid overtightening, which can crack polypropylene threads.
