Globally Manufactured 150# FNPTxFNPT Malleable Black Iron Pipe Reducing Coupling

Globally Manufactured 150# FNPTxFNPT Malleable Black Iron Pipe Reducing Coupling

The Globally Manufactured 150# FNPTxFNPT Malleable Black Iron Pipe Reducing Coupling is a durable threaded fitting designed to connect two different sizes of male-threaded pipe or piping components in a compact, efficient connection. Manufactured from strong malleable black iron, this Class 150 reducing coupling features Female National Pipe Thread (FNPT) connections on both ends, making it a practical choice for commercial, mechanical, industrial, utility, and general-purpose piping systems.

FNPTxFNPT Reducing Pipe Connection

The FNPTxFNPT configuration provides female tapered pipe threads at both ends of the fitting. Because each end has a different nominal connection size, the reducing coupling allows a larger threaded pipe to transition directly to a smaller threaded pipe.

Using an integral reducing coupling can eliminate the need for a standard coupling combined with a separate reducing bushing or adapter. Fewer components can help reduce the number of threaded joints, shorten the overall connection, simplify installation, and create a cleaner piping layout.

Durable Class 150 Malleable Iron Construction

Class 150 black malleable iron reducing couplings provide the strength and toughness required for many industrial and commercial threaded piping applications. Malleable iron construction offers dependable mechanical performance while threaded connections allow convenient field installation without welding at the fitting joint.

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 fitting size, temperature, conveyed media, applicable standards, and manufacturer specifications.

Industrial and Commercial Applications

Typical applications include:

• Industrial plant piping

• Mechanical piping systems

• Compressed-air lines

• Utility piping

• Equipment connections

• Commercial construction

• Maintenance and repair

• Threaded pipe-size transitions
