Nomaco 438131a Schedule 40 Spigot X Fipt Bushing

Product Description

The NOMACO 438131a is a Schedule 40 reducing bushing with a spigot inlet and female iron pipe thread (FIPT) outlet. It steps down from a 1-inch connection to a 3/4-inch threaded fitting, making it a practical adapter in pressurized piping systems. Schedule 40 construction provides the wall thickness required for standard residential and light commercial pressure service. Licensed plumbers and pipefitters install this bushing when connecting threaded female fittings to spigot-end pipe sections of differing sizes.

This bushing is suited for water supply, irrigation, and general plumbing distribution lines where a size reduction from 1 inch to 3/4 inch is needed at a threaded joint. The spigot end slips into a socket fitting of the corresponding size, while the FIPT end accepts a male-threaded fitting or valve. Typical install scenarios include branch takeoffs, valve connections, and zone transitions in both residential and light commercial systems.

Key Features

• Schedule 40 wall thickness rated for standard pressure service
• Spigot inlet fits directly into a 1-inch socket fitting
• FIPT outlet accepts standard 3/4-inch male-threaded fittings
• Compact bushing profile reduces need for additional couplings
• Single-piece construction with no moving parts or seals to replace

Compatibility

Designed as an OEM-style Schedule 40 reducing bushing for use in standard 1-inch spigot to 3/4-inch FIPT piping configurations in residential and light commercial plumbing and irrigation systems.

Installation Notes

Installation is performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the supply line before disassembling any existing fittings. Apply thread sealant tape or compound to the male threads mating to the FIPT end before tightening. Hand-tighten first, then use appropriate pipe wrenches; avoid over-torquing, which can crack fittings.
