Bk Mueller 511-985HN Hex Pipe Bushing 2 X 1 Inch

Product Description

The BK MUELLER 511-985HN is a galvanized malleable iron hex bushing designed to reduce pipe diameter in threaded piping systems. At 2 inches by 1 inch, it transitions a 2-inch female NPT fitting down to a 1-inch male NPT connection. Rated for 300 psi on liquid and gas service and 150 psi on steam service, this Class 150 fitting handles demanding pressure applications in both commercial and residential plumbing and gas distribution systems. The galvanized finish provides corrosion resistance. Plumbers and pipefitters install this bushing as part of threaded iron pipe assemblies.

This hex bushing is used in residential and commercial piping systems wherever a threaded diameter reduction is required. Typical applications include gas distribution lines, water supply piping, compressed air systems, and steam service installations. The hex profile allows standard pipe wrenches to achieve proper seating torque. It is appropriate for new construction and retrofit work where existing iron pipe runs require a reduction fitting at a branch or equipment connection point.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements for gas service. Shut off all gas or water supply and depressurize the system completely before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape to the male threads before assembly. Do not overtighten; use a pipe wrench on the hex flats and do not apply force to the pipe body.
