The BMI USA 6058 is a lead-free brass threaded coupling designed for joining pipe sections in plumbing and mechanical systems. Built from solid brass, this coupling delivers reliable, corrosion-resistant connections in both hot and cold water supply lines. The threaded design allows for straightforward installation using standard pipe wrenches, making it a practical choice for licensed plumbers working on residential and light commercial projects. At 5.34 pounds, the fitting reflects the substantial brass construction expected of a durable, long-service coupling in this size range.
This coupling is suited for plumbing applications where a 4-inch to 2-inch threaded connection is required. Typical install scenarios include supply line transitions, retrofit piping work, and mechanical room rough-in where reducing couplings are needed to connect pipe runs of differing diameters. The lead-free construction meets safe drinking water requirements, making it appropriate for potable water systems.
Designed as an OEM-style threaded brass coupling for use in standard residential and commercial plumbing systems requiring a 4-inch by 2-inch threaded reducing connection.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before beginning work. Use appropriate thread sealant or PTFE tape on all threaded connections and tighten with a pipe wrench to a snug, leak-free fit. Do not over-torque, as this may damage the threads or fitting body.
