Bmi Usa 6312 Brass 90 Degree Elbow 4 Inch Lead Free

Product Description

The BMI USA 6312 is a 4-inch lead-free brass 90-degree threaded elbow fitting designed for use in potable water, hydronic, and plumbing piping systems. Constructed from solid brass, this elbow provides a reliable directional change in threaded pipe runs where a 90-degree turn is required. The lead-free construction meets the requirements of NSF/ANSI 61 and applicable Safe Drinking Water Act provisions, making it appropriate for domestic water supply applications. Licensed plumbers and pipefitters rely on this type of fitting in both new construction and retrofit work where a durable, pressure-rated threaded connection is needed.

This fitting is suited for residential and light commercial plumbing applications. The 4-inch size accommodates larger-diameter pipe runs typical of main supply lines, mechanical room distribution headers, and commercial water service connections. It is compatible with standard NPT-threaded pipe and fittings of the same diameter and is installed wherever a 90-degree change in pipe direction is required in a threaded piping system.

Key Features

• Lead-free brass construction meets Safe Drinking Water Act requirements for potable water use
• 90-degree elbow geometry for directional changes in threaded pipe runs
• 4-inch size suitable for larger main supply and distribution piping
• Solid brass material provides corrosion resistance and long service life
• Standard NPT threaded connections for compatibility with common pipe and fittings

Compatibility

Designed as an OEM-style replacement and standard-fit threaded fitting for 4-inch NPT plumbing systems in residential and commercial installations.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water supply line before removing any existing fitting or making new connections. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten fittings to a secure fit without overtightening, which can crack brass fittings. Verify all connections for leaks after restoring system pressure.
