Asc Engineered Solutions 2X1.BB Hex Head Pipe Bushing

Product Description

The ASC Engineered Solutions 2X1.BB is a hex head pipe bushing rated for 125 lb service, machined from cast iron with a black finish. It is used to reduce a 2-inch female threaded port down to a 1-inch male threaded connection using a standard MNPT x FNPT end configuration. The hex head design allows a wrench to be applied directly to the bushing body for secure installation without slipping. Plumbers and pipefitters install this fitting in gas, water, and steam distribution systems where pipe diameter reductions are required at a threaded joint.

This bushing is suited for residential and light commercial piping applications. The 2-inch nominal FNPT inlet accepts a standard 2-inch threaded pipe or fitting, while the 1-inch nominal MNPT outlet transitions to a smaller-diameter run. Cast iron construction and a 125 lb pressure class make it appropriate for low-pressure steam, gas distribution, and water supply systems where threaded cast iron fittings are specified.

Key Features

• Hex head body allows wrench engagement for secure, leak-free tightening
• Cast iron construction rated for 125 lb service class
• MNPT x FNPT thread configuration for standard threaded pipe connections
• 2 x 1 inch nominal size reduces pipe diameter at a single threaded joint
• Black finish suitable for gas and water piping applications
• Domestic manufacture

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 125 lb cast iron threaded piping systems using 2-inch to 1-inch reducing connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable code requirements such as the IPC or IFGC. Shut off and depressurize the supply line completely before making or breaking any threaded connections. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly and tighten with a pipe wrench applied to the hex head. Do not overtighten cast iron fittings, as the material is brittle and susceptible to cracking under excessive torque.
