B K/mueller Inds(import) 521-986HC Black Hex Bushing

Product Description

The B K/MUELLER INDS(IMPORT) 521-986HC is a black hex bushing designed to reduce pipe thread sizes in threaded piping systems. Sized at 2 inches by 1-1/4 inches, this bushing steps down from a 2-inch female thread to a 1-1/4-inch male thread. The hex profile allows for wrench-on installation, providing the torque needed to seat the fitting properly. It ships in a package quantity of 5, making it practical for service vehicles and job-site stock. Licensed plumbers and pipefitters install this type of fitting in gas, water, and general piping applications.

Black hex bushings in this size range are standard in residential and light commercial piping work. Common scenarios include gas line branch reductions, black iron piping systems, and mechanical room distribution headers where pipe sizes must be stepped down at fixture or appliance connections. The black iron finish is suited for above-grade gas piping applications where galvanized fittings are not required by code.

Key Features

• 2-inch female NPT to 1-1/4-inch male NPT thread reduction
• Hex outer profile for wrench installation and secure seating
• Black finish suitable for gas and general iron piping systems
• Sold in a package quantity of 5 pieces
• Compact bushing form factor reduces fitting count versus coupling-and-nipple combinations

Compatibility

Designed as an OEM-style threaded fitting for use in standard NPT black iron piping systems in residential and commercial plumbing and gas distribution applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable local plumbing and gas codes, including IFGC guidelines for gas piping. Shut off gas or water supply and depressurize the line before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to male threads before assembly. Use a pipe wrench on the hex profile to achieve a leak-free connection without over-stressing the fitting.
