Green Leaf Rb 34-18 P Reducer Bushing 3/4 X 1/8 in Mipt Fipt

Product Description

The GREEN LEAF RB 34-18 P is a polypropylene reducer bushing designed to transition between a 3/4-inch male iron pipe thread (MIPT) and a 1/8-inch female iron pipe thread (FIPT) connection. This black polypropylene fitting reduces pipe diameter within a threaded assembly, making it a reliable choice for water distribution, chemical handling, and low-pressure plumbing systems. Certified to NSF 61 and NSF 372, it meets drinking water contact and lead-free standards. Plumbers and pipefitters install this fitting when reducing branch lines or adapting threaded pipe runs to smaller-diameter components.

This reducer bushing suits residential and light commercial plumbing applications where a threaded polypropylene fitting is preferred over metal for corrosion resistance or chemical compatibility. Typical installations include potable water supply lines, irrigation manifolds, and fluid-handling systems that require a step-down from 3/4-inch to 1/8-inch threaded connections. Its black polypropylene construction handles a range of process fluids without the corrosion concerns associated with metal fittings.

Key Features

• Reduces 3/4-inch MIPT to 1/8-inch FIPT in a single threaded fitting
• Polypropylene construction resists corrosion and chemical attack
• NSF 61 certified for drinking water system components
• NSF 372 certified for lead-free compliance
• Black color for easy identification in mixed-material systems
• Threaded MIPT x FIPT end connections for tool-installable, leak-resistant assembly

Compatibility

Designed as an OEM-style threaded reducer bushing for use in standard NPT threaded plumbing assemblies requiring a 3/4-inch to 1/8-inch pipe size reduction.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with the International Plumbing Code (IPC). Shut off and depressurize the water supply before disassembling any threaded connections. Apply thread sealant tape or compound rated for use with polypropylene fittings to all male threads before assembly. Do not over-torque polypropylene fittings, as the material is subject to cracking under excessive wrench force.
