Sigma 819907809 Hex Head Pipe Bushing 2x3/4 in 150lb Galvanized

Product Description

The SIGMA 819907809 is a standard hex head pipe bushing designed to reduce a 2-inch male NPT connection down to a 3/4-inch female NPT port. Constructed from malleable iron with a galvanized finish, this bushing is rated for 150 lb service and is built for durability in piping systems where corrosion resistance and mechanical strength are required. The hex head profile allows for wrench engagement during installation, making it a practical fitting for tight or high-torque applications. It is commonly installed by licensed plumbers and pipefitters working on water, gas, or low-pressure steam distribution systems.

This bushing is suited for residential and light commercial piping installations where a threaded reduction is needed between two pipe sizes. Typical applications include water supply lines, compressed air systems, and gas piping where reducing fittings are required to transition from a 2-inch main to a 3/4-inch branch or fixture connection. The galvanized coating provides added protection against rust in exposed or mildly corrosive environments.

Key Features

• 2-inch MNPT to 3/4-inch FNPT reduction in a single fitting
• 150 lb pressure rating suitable for water, gas, and low-pressure steam service
• Malleable iron construction for strength and impact resistance
• Galvanized finish for corrosion protection in exposed or damp environments
• Hex head design allows secure wrench grip during installation
• Standard NPT threads ensure compatibility with common threaded pipe and fittings

Compatibility

Designed as a standard OEM-style threaded reducing bushing for use in 150 lb malleable iron piping systems with NPT-threaded components.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten using a pipe wrench on the hex head. Do not overtighten, as malleable iron fittings can crack if excessive force is applied.
