Bmi Usa 35157 Black Hex Bushing 4in X 2.5in

Product Description

The BMI USA 35157 is a malleable iron hex bushing with a black finish, designed to reduce pipe connections from a 4-inch female thread to a 2.5-inch male thread. This type of bushing is a standard fitting used in piping systems to adapt between two different pipe sizes within the same run. The hex profile allows for wrench engagement during installation, ensuring a secure, leak-free makeup. Licensed plumbers and pipefitters install this fitting in a wide range of water, gas, and industrial fluid piping applications.

This hex bushing is suited for use in residential and commercial plumbing, gas distribution, and mechanical piping systems where a threaded size reduction is required. The malleable iron construction provides durability and resistance to mechanical stress, making it appropriate for both above-ground and interior piping installations. It is commonly used wherever black iron pipe is specified, including gas supply lines and general plumbing rough-in work.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the IPC and IFGC where relevant. Shut off and depressurize the piping system before making or breaking any threaded connections. Apply an appropriate thread sealant or PTFE tape to male threads prior to assembly. Do not over-tighten; use the hex body to apply controlled torque with a properly sized wrench.
