Sigma 819907692 Hex Head Pipe Bushing 2x1-1/2 in 150lb Galvanized

Product Description

The SIGMA 819907692 is a FIG 3383 standard hex head pipe bushing designed to reduce pipe thread connections from a 2-inch male NPT to a 1-1/2-inch female NPT. Constructed from malleable iron with a galvanized finish, this bushing carries a 150 lb pressure rating suitable for low-pressure water, air, and gas piping systems. The hex head design allows for wrench engagement during installation, making it straightforward to achieve a proper seal without slipping. Plumbers and pipefitters rely on this type of fitting when transitioning between pipe sizes in threaded metallic piping assemblies.

This bushing is intended for use in residential and light commercial plumbing, HVAC piping, and industrial threaded pipe systems where a concentric, in-line size reduction is needed. It is threaded on the outside with a 2-inch MNPT and on the inside with a 1-1/2-inch FNPT, allowing direct installation into a tee, coupling, or other female-threaded fitting. The galvanized coating provides corrosion resistance for wet or outdoor service environments. This is an import-grade fitting appropriate for general-purpose piping work.

Key Features

• Hex head design allows wrench engagement for controlled installation torque
• 2-inch MNPT outer thread reduces to 1-1/2-inch FNPT inner thread
• 150 lb pressure class rating for low-pressure piping service
• Malleable iron construction provides strength and impact resistance
• Galvanized finish resists corrosion in wet and exposed environments
• Concentric design keeps piping runs in-line without offset

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 150 lb threaded malleable iron piping systems using NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten, as malleable iron threads can crack under excessive force.
