Bmi Usa 20403 Black Malleable Iron Pipe Tee 3/8 in Xh

Product Description

The BMI USA 20403 is a 3/8-inch extra heavy black malleable iron pipe tee designed for threaded pipe assemblies in gas, steam, and industrial piping systems. Malleable iron construction gives the fitting the ductility needed to absorb vibration and mechanical stress without cracking, while the extra heavy wall thickness provides added pressure capacity over standard fittings. The black finish is standard for gas service applications. Licensed pipefitters and plumbers install this fitting where a branch connection is required in a straight run of threaded pipe.

This tee is suited for residential and light commercial gas piping, steam distribution, and compressed air systems where extra heavy malleable iron fittings are specified. The 3/8-inch size fits standard NPT-threaded pipe of the same nominal diameter. Extra heavy class fittings are commonly called out on job specs that require heavier wall stock than standard 150-class fittings.

Key Features

• Extra heavy malleable iron construction for increased pressure and mechanical durability
• Black finish suitable for gas service piping installations
• 3/8-inch nominal size with standard NPT-threaded connections
• Ductile malleable iron resists cracking under vibration and stress

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded 3/8-inch NPT pipe systems requiring extra heavy class malleable iron tees.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where required. Shut off gas or system pressure and verify the line is depressurized before disassembling or installing any threaded fitting. Apply an approved thread sealant or PTFE tape rated for the intended service medium to all male threads before assembly. Do not over-tighten; use a pipe wrench to achieve a secure, leak-free joint without stressing the fitting body.
