Asc Engineered Solutions 1.BP Cast Iron Pipe Plug 1 in Mnpt

Product Description

The ASC Engineered Solutions 1.BP is a cored regular square head pipe plug designed to seal threaded pipe openings in low-pressure piping systems. Cast from black cast iron and rated at 125 lb, this plug features a 1-inch nominal male NPT (MNPT) end for direct thread-in installation. The square head drive design allows for installation and removal with standard hand tools. Plumbers and pipefitters use this type of plug to cap off branch lines, test ports, and unused tee or cross outlets during system assembly or pressure testing.

This plug is suited for use in residential and light commercial plumbing, HVAC hydronic, and gas distribution piping systems where a 1-inch MNPT threaded termination is required. The cored design reduces material weight while maintaining structural integrity at the rated pressure class. Black cast iron construction is appropriate for use in black iron gas piping systems as well as non-corrosive water and hydronic applications. Domestic manufacture meets common project specification requirements for U.S.-sourced components.

Key Features

• 1-inch nominal MNPT thread for direct installation into female-threaded fittings or pipe
• 125 lb pressure class cast iron construction
• Square head drive accepts standard wrenches for installation and removal
• Cored regular pattern reduces weight while maintaining rated performance
• Black finish suitable for use in black iron gas and hydronic piping systems

Compatibility

Designed as an OEM-style threaded pipe plug for use in 1-inch MNPT female-threaded cast iron, malleable iron, or steel pipe fittings rated at 125 lb 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 removing or installing any threaded plug. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before installation. Do not overtighten; use a properly sized pipe wrench on the square head to achieve a leak-free seal without cracking the casting.
