Asc Engineered Solutions 1BX1.BB Hex Head Pipe Bushing

Product Description

The ASC Engineered Solutions 1BX1.BB is a hex head pipe bushing designed to reduce a 1-1/4 inch male NPT threaded pipe or fitting down to a 1 inch female NPT connection. Constructed from malleable iron with a black finish, this bushing is rated for 150 lb service pressure and is manufactured domestically. The hex head profile provides a flat wrench surface for secure installation and easy removal without damaging adjacent fittings. Plumbers and pipefitters use this style of bushing regularly when adapting between two different pipe sizes within a threaded pipe system.

This bushing is suited for use in residential and light commercial plumbing, gas distribution, steam, and hydronic heating systems where a threaded reduction is required. The MNPT x FNPT end configuration allows it to thread directly into a female-threaded fitting or valve body on the larger end while accepting a male-threaded pipe or nipple on the smaller end. It is commonly installed in mechanical rooms, boiler rooms, and utility piping systems where malleable iron fittings are the specified standard.

Key Features

• Hex head design provides flat wrench surfaces for controlled installation torque
• 1-1/4 inch MNPT to 1 inch FNPT configuration for direct in-line pipe size reduction
• 150 lb pressure rating suitable for standard plumbing and gas piping applications
• Malleable iron construction for durability and resistance to mechanical stress
• Black finish standard for gas and steam service applications
• Domestic manufacture

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 150 lb malleable iron threaded pipe systems using NPT thread standards.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the International Plumbing Code or International Fuel Gas Code where relevant. Shut off and depressurize the system before installing or removing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-torque the bushing, as malleable iron fittings can crack under excessive force.
