Asc Engineered Solutions D.BMSL 1/2 in Street Elbow 150 Lb

Product Description

The ASC Engineered Solutions D.BMSL is a 1/2 inch nominal malleable iron street elbow designed for low-pressure gas, air, and fluid piping systems. It features a male NPT (MNPT) inlet on one end and a female NPT (FNPT) outlet on the other, allowing a direct street-style connection without the need for an additional coupling or fitting. Rated at 150 lb, this elbow handles typical residential and light commercial service pressures. The black finish is standard for gas-service fittings. Domestic manufacture supports compliance requirements on projects with country-of-origin specifications.

Street elbows like the D.BMSL are used wherever a 90-degree directional change is needed in a threaded pipe run and space is tight. Common applications include natural gas and propane distribution piping, compressed air lines, and water service roughed in with threaded black iron pipe. Plumbers, pipefitters, and HVAC technicians regularly use this fitting when connecting appliances such as furnaces, boilers, unit heaters, and gas ranges to the supply branch.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable codes such as the IFGC or IPC. Shut off the gas or fluid supply and depressurize the line before removing any existing fittings or making new connections. Apply listed pipe thread sealant or PTFE tape rated for the service medium to all male threads before assembly.
