Bmi Usa 35631 Malleable Iron Pipe Cross 3 Inch Black

Product Description

The BMI USA 35631 is a 3-inch malleable iron pipe cross finished in black, designed for use in low-pressure piping systems across plumbing, gas distribution, and mechanical applications. A pipe cross fitting connects four sections of pipe at a single junction point, allowing flow to branch in three directions from one central body. At 7.29 pounds, the malleable iron construction provides the toughness and thread-holding strength that trade professionals expect in demanding piping installations. This fitting is typically installed by licensed plumbers and pipefitters working on threaded iron pipe systems.

This pipe cross is suited for residential and light commercial piping configurations where a four-way threaded junction is required. Common applications include natural gas distribution lines, steam systems, compressed air headers, and water supply piping where malleable iron fittings are specified. The black finish is standard for gas line work in many jurisdictions, making this fitting a go-to choice for gas piping rough-in and service work.

Key Features

• Four-way pipe cross configuration for branching threaded iron pipe runs
• Malleable iron construction for strength and machinability in threaded connections
• Black finish commonly specified for gas distribution piping
• 3-inch fitting size suitable for main distribution lines and large branch headers
• Threaded connections compatible with standard NPT iron pipe

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3-inch threaded iron pipe systems using standard NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including IFGC and IPC requirements for gas and plumbing systems respectively. Shut off all gas or fluid supply and relieve system pressure completely before disassembling or installing any threaded pipe fitting. Apply an approved pipe thread sealant or PTFE tape rated for the intended service to all male threads before assembly. Do not overtighten threaded connections, as malleable iron fittings can crack if excessive force is applied.
