Bk Mueller 510-187HC Malleable Iron 90 Reducing Elbow

Product Description

The BK MUELLER 510-187HC is a malleable iron 90-degree reducing elbow designed for threaded pipe systems handling liquid, gas, and steam service. It transitions from a 2-inch pipe to a 1.5-inch pipe while making a full 90-degree direction change. Rated at 300 psi for liquid and gas and 150 psi for steam, this Class 150 fitting carries a galvanized finish coating for corrosion resistance. It is installed by licensed plumbers, pipefitters, and mechanical contractors on both new construction and retrofit projects.

This fitting is suited for residential and commercial piping systems where a change in pipe direction and a reduction in pipe size are required in a single fitting. Common applications include natural gas distribution lines, compressed air systems, steam distribution, and general liquid service piping. The galvanized coating makes it appropriate for exposed or moderately corrosive environments. It connects using standard NPT threaded pipe ends.

Key Features

• 90-degree reducing elbow combines direction change and pipe size reduction in one fitting
• Rated 300 psi for liquid and gas service
• Rated 150 psi for steam service
• Class 150 malleable iron construction for durability under thermal cycling and mechanical stress
• Galvanized finish coating for corrosion resistance
• 2 x 1.5 inch fitting size for standard NPT threaded pipe

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Class 150 malleable iron threaded pipe systems using standard NPT connections in liquid, gas, and steam service applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and IFGC code requirements for the service type. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for the service medium before assembly. Do not over-tighten threaded connections, as malleable iron fittings can crack under excessive torque.
