Sigma 819908286 Hex Head Pipe Bushing 3x2 in 150lb Galvanized

Product Description

The SIGMA 819908286 is a standard hex head pipe bushing designed to reduce a 3-inch male NPT connection down to a 2-inch female NPT connection. This fitting is rated at 150 lb and is manufactured from galvanized malleable iron, making it suitable for use in low-pressure piping systems where corrosion resistance and mechanical durability are required. The hex head profile provides a flat wrench surface for easy torquing into place. This bushing is a standard plumbing and pipefitting component installed by licensed plumbers and pipefitters in commercial and residential applications.

This bushing is used in threaded pipe assemblies where a transition from a larger-diameter pipe to a smaller-diameter pipe is needed within the same run. Typical applications include water supply systems, low-pressure gas distribution, and general industrial piping. The MNPT x FNPT end configuration allows it to thread directly into a female-threaded fitting or valve body while accepting a male-threaded pipe on the outlet side. The galvanized finish provides additional protection against rust and corrosion in exposed or mildly corrosive environments.

Key Features

• 3-inch MNPT inlet to 2-inch FNPT outlet for in-line pipe size reduction
• 150 lb pressure rating suitable for low-pressure threaded piping systems
• Malleable iron construction provides toughness and resistance to impact
• Galvanized finish adds corrosion protection for wet or exposed installations
• Hex head design allows standard wrench engagement for installation and removal
• Conforms to standard FIG 3383 hex head bushing specifications

Compatibility

Designed as an OEM-style replacement or standard component for use in 150 lb malleable iron threaded piping systems requiring a 3-inch to 2-inch pipe reduction with NPT threading.

Installation Notes

Installation is performed by a licensed plumber or pipefitter using pipe wrenches and appropriate thread sealant tape or compound rated for the service fluid. Always de-pressurize and drain the system before removing or installing threaded fittings. Tighten to hand-tight plus the appropriate number of turns per thread engagement guidelines without over-torquing malleable iron fittings to avoid cracking. Verify that the thread form and pressure rating are compatible with the existing system before installation.
