Asc D.BP Cored Square Head Plug 1/2 Inch Mnpt Cast Iron

Product Description

The ASC Engineered Solutions D.BP is a cored regular square head plug designed to close off threaded pipe ends in low-pressure piping systems. Manufactured from cast iron with a black finish, it features a male NPT (MNPT) end style rated at 125 lb. The square head profile provides a solid grip surface for installation with a wrench. This type of plug is a standard component in gas, water, and industrial piping assemblies and is typically installed by licensed plumbers, pipefitters, and mechanical contractors working on ferrous pipe systems.

The D.BP is sized at 1/2 inch nominal and fits standard MNPT threaded pipe connections. It is suited for use in residential and light commercial piping applications where a 125 lb cast iron fitting is specified. The black finish is standard for cast iron pipe fittings used in gas distribution and water supply rough-in work. Domestic manufacture supports project requirements that call for domestically produced pipe fittings.

Key Features

• Cored square head design provides wrench-flat engagement for controlled installation torque
• 125 lb pressure class cast iron construction for standard service piping
• 1/2 inch nominal MNPT thread for compatibility with standard NPT pipe fittings
• Black cast iron finish standard for gas and water piping applications
• Domestically manufactured to support Buy American and project compliance requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch nominal MNPT threaded cast iron pipe systems rated at 125 lb service class.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements. Shut off and depressurize the piping system completely before installing or removing threaded plugs. Apply an approved pipe thread sealant or PTFE tape to the male threads prior to installation. Do not overtighten cast iron fittings, as the material is brittle and susceptible to cracking under excessive force.
