Sigma 819907726 Hex Head Pipe Bushing 1-1/4x2 in 150lb Galvanized

Product Description

The SIGMA 819907726 is a FIG 3383 hex head pipe bushing designed to reduce a 2-inch female NPT fitting down to a 1-1/4-inch male NPT connection. Constructed from malleable iron with a galvanized finish, this bushing is rated for 150 lb service and provides a reliable, corrosion-resistant threaded transition in pressurized pipe systems. The hex head design allows standard wrench engagement for proper torque during installation. Plumbers and pipefitters use this fitting in water supply, hydronic heating, and general industrial piping applications where a threaded reducer bushing is required.

This bushing is suited for residential and light commercial piping installations where a reduction from 2-inch to 1-1/4-inch threaded connections is needed. The MNPT x FNPT end configuration threads directly into a female pipe fitting or valve and accepts a male-threaded pipe or fitting on the outlet side. It is commonly installed in supply lines, branch connections, and equipment tie-ins on galvanized or black iron pipe systems. The galvanized coating adds protection against rust in exposed or moist environments.

Key Features

• FIG 3383 hex head design allows wrench engagement for secure installation
• 1-1/4 inch MNPT inlet to 2 inch FNPT outlet threaded reducer configuration
• 150 lb pressure rating suitable for standard commercial and residential service
• Malleable iron construction provides strength and impact resistance at threaded joints
• Galvanized finish resists corrosion in exposed or damp installation environments

Compatibility

Designed as an OEM-style replacement or standard fitting for 150 lb malleable iron threaded pipe systems using NPT connections in plumbing, hydronic, and industrial piping applications.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC and IFGC code requirements. Shut off and depressurize the pipe system fully before removing or installing any threaded fitting. Apply thread sealant tape or pipe compound to the male threads before engagement, and use a pipe wrench on the hex head to tighten to a leak-free connection without over-stressing the fitting. Do not use this fitting beyond its rated pressure class or in applications requiring a higher pressure rating.
