Globally Manufactured 150# MNPT Malleable Black Iron Pipe Cored Bar Plug
Globally Manufactured 150# MNPT Malleable Black Iron Pipe Cored Bar Plug
The Globally Manufactured 150# MNPT Malleable Black Iron Pipe Cored Bar Plug is a durable threaded fitting designed to close or terminate a female-threaded pipe opening in compatible industrial, commercial, mechanical, and utility piping systems. Manufactured from strong malleable black iron, this Class 150 pipe plug features a Male National Pipe Thread (MNPT) connection and a bar-style head designed to provide a practical gripping surface for installation and removal.
MNPT Cored Bar Plug Connection
The MNPT connection allows the plug to thread directly into a compatible Female National Pipe Thread (FNPT) fitting, valve, manifold, equipment port, or other threaded opening. Unlike a pipe cap, which installs over a male-threaded pipe or nipple, a male pipe plug threads into the female opening, creating a compact closure.
The cored bar plug design incorporates an internally recessed or hollowed section formed during manufacturing. The external bar-style head provides an accessible gripping surface for applying installation or removal torque with an appropriate tool.
Durable Class 150 Malleable Iron Construction
Class 150 black malleable iron cored bar plugs combine strength, toughness, and convenient threaded installation. Their removable design makes them particularly useful for openings that may require future access for inspection, cleaning, maintenance, testing, equipment servicing, or system expansion.
The 150# or Class 150 designation identifies the fitting class rather than a universal 150 PSI maximum working pressure. Proper selection should consider nominal pipe size, operating pressure, temperature, conveyed media, thread compatibility, applicable piping standards, and manufacturer specifications.
Industrial and Commercial Applications
Common applications include industrial plant piping, compressed-air systems, mechanical piping, utility lines, manifolds, equipment connections, commercial construction, machinery installations, maintenance operations, and unused threaded outlet closures.
Dependable Class 150 Cored Bar Plug
For contractors, industrial buyers, OEMs, and MRO professionals, the Globally Manufactured 150# MNPT Malleable Black Iron Pipe Cored Bar Plug provides an economical combination of MNPT connectivity, compact pipe closure, convenient bar-head access, durable malleable iron construction, and dependable threaded piping performance.
