Bmi Usa 20019 Black Malleable Iron Pipe Coupling 1/2 X 3/8 in

Product Description

The BMI USA 20019 is a black extra heavy malleable iron pipe coupling designed for high-pressure piping applications in residential and commercial systems. Finished in black and built to extra heavy (XH) wall specifications, this reducer coupling connects a 1/2 inch pipe to a 3/8 inch pipe. The malleable iron construction provides superior toughness compared to standard cast iron, making it suitable for demanding mechanical and gas piping installations. Licensed plumbers and pipefitters typically install this type of fitting as part of threaded iron pipe assemblies where a step-down connection is required.

This coupling reducer is appropriate for use in threaded black iron pipe systems, including gas distribution, compressed air, and industrial fluid piping. The extra heavy wall rating makes it a practical choice where elevated operating pressures or mechanical stress are present. It is installed in both new construction and retrofit piping runs where a 1/2 inch to 3/8 inch reduction is needed in a malleable iron threaded system.

Key Features

• Extra heavy (XH) wall construction for higher pressure service
• Black finish — standard for gas and industrial pipe systems
• Malleable iron material offers improved impact resistance over standard cast iron
• 1/2 inch to 3/8 inch reducer configuration for step-down pipe connections
• Threaded fitting design compatible with standard NPT threaded pipe

Compatibility

Designed as an OEM-style replacement fitting for use in threaded black iron pipe systems requiring a 1/2 inch to 3/8 inch reduction in extra heavy wall configurations.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code (IPC), or the International Fuel Gas Code (IFGC) where applicable. Shut off the gas or fluid supply and depressurize the line before beginning any fitting work. Apply an appropriate thread sealant or PTFE tape to all NPT threads before assembly. Do not over-torque the fitting, as malleable iron threads can be damaged by excessive force.
