Globally Manufactured 150# FNPT Malleable Black Iron Pipe Cap

Globally Manufactured 150# FNPT Malleable Black Iron Pipe Cap

The Globally Manufactured 150# FNPT Malleable Black Iron Pipe Cap is a durable threaded fitting designed to close and terminate the end of a male-threaded pipe or pipe nipple. Manufactured from strong malleable black iron, this Class 150 pipe cap features a Female National Pipe Thread (FNPT) connection for convenient installation in commercial, mechanical, industrial, utility, and general-purpose piping systems.

FNPT Threaded Pipe End Closure

The FNPT black iron pipe cap threads directly onto a compatible Male National Pipe Thread (MNPT) pipe, nipple, or fitting connection. Its closed-end design provides a simple method for terminating a piping run, closing an unused connection, or creating an accessible endpoint for future piping system expansion.

Unlike a permanent welded closure, a threaded pipe cap can be removed when access to the piping system is required. This makes malleable iron pipe caps useful for maintenance, system modifications, testing, equipment installations, and future branch extensions.

Durable Class 150 Malleable Iron Construction

Class 150 black malleable iron pipe caps combine strength, toughness, and convenient threaded installation. Malleable iron construction provides dependable mechanical performance for a wide range of compatible industrial and commercial piping applications.

The 150# or Class 150 designation identifies the fitting class and should not be interpreted as a universal 150 PSI maximum working pressure. Actual allowable pressure depends on pipe size, operating temperature, conveyed media, applicable standards, and manufacturer specifications.

Industrial and Commercial Applications

Common applications include:

• Industrial plant piping

• Mechanical piping systems

• Compressed-air lines

• Utility piping

• Equipment connections

• Commercial construction

• Maintenance and repair

• Temporary or permanent pipe termination
