Bmi Usa 35057 Black Malleable Iron Pipe Coupling

Product Description

The BMI USA 35057 is a black malleable iron pipe coupling designed for joining pipe sections in plumbing, gas, and general piping systems. Manufactured from malleable iron with a black finish, this coupling delivers the durability and corrosion resistance that trade professionals expect in demanding installations. At 4 inches by 2.5 inches, it suits a range of threaded pipe configurations and is installed by licensed plumbers, pipefitters, and HVAC technicians working on commercial and residential systems.

This coupling is suited for use in residential and light commercial piping applications where a reliable, code-compliant threaded connection is required. The black malleable iron construction makes it appropriate for gas distribution lines, compressed air systems, and general-purpose pipe runs where black iron fittings are specified. It is a standard fitting type stocked by plumbing and mechanical contractors for routine installations and service calls.

Key Features

• Black malleable iron construction for strength and durability in threaded piping systems
• Black finish suitable for gas, air, and general-purpose piping applications
• 4 x 2.5 inch sizing for connecting appropriately sized threaded pipe sections
• Standard coupling form factor for straightforward replacement or new installation

Compatibility

Designed as an OEM-style replacement or standard-use fitting for threaded black iron pipe systems in residential and commercial plumbing and mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the International Plumbing Code (IPC) and International Fuel Gas Code (IFGC) where gas service is involved. Shut off the gas or water supply and relieve system pressure fully before disassembling or installing any pipe fitting. Apply appropriate thread sealant or PTFE tape to all threaded connections before assembly. Do not over-tighten threaded fittings, as malleable iron threads can crack under excessive force.
