Parker PT-01089 Pipe Adapter Mnptf X Npsm Steel

Product Description

The PARKER PT-01089 is a steel industrial pipe adapter designed to connect a 3/4-14 female thread to a 1-11-1/2 male thread using an MNPTF x NPSM connection type. This adapter is used to transition between two different thread standards in a piping system, allowing a straight mechanical seal on the NPSM side to mate with a tapered female thread on the MNPTF side. Built from steel, it is suited for industrial piping applications where thread-to-thread transitions are required. Licensed plumbers and pipefitters are the typical installers for this type of fitting in both commercial and industrial service environments.

This adapter fits inline piping configurations that require a reduction or transition between a 3/4-14 thread and a 1-11-1/2 thread. The MNPTF x NPSM configuration makes it appropriate for use in hydraulic, pneumatic, or fluid transfer lines where these two thread forms must be joined. It is sold in package quantities of five, making it practical for service contractors and maintenance operations that install multiple connections in a single job.

Key Features

• Steel construction for durability in industrial piping environments
• 3/4-14 female thread (MNPTF) transitions to 1-11-1/2 male thread (NPSM)
• MNPTF x NPSM connection type for cross-standard thread mating
• Compact profile at 1.8 inches length and 2.17 inches width
• Packaged in quantities of five for multi-connection jobs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial piping systems requiring an MNPTF x NPSM thread adapter with 3/4-14 female and 1-11-1/2 male thread sizes.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC or IFGC guidelines for threaded pipe connections. Shut off and depressurize the line completely before removing or installing any threaded fittings. Apply appropriate thread sealant or tape to the tapered threads as required by the connection type. Do not overtighten steel fittings, as this can damage threads or crack adjacent components.
