Parker PT-00050 Pipe Adapter 1-1/4 in Mnptf X Fnptf Steel

Product Description

The PARKER PT-00050 is a steel industrial pipe adapter designed to connect male and female NPT threaded pipe connections in a single inline fitting. Built for demanding service, it carries a 2500 psi pressure rating, making it suitable for high-pressure fluid and pneumatic systems. The adapter transitions between a 1-1/4 inch MNPTF male thread and a 1-1/4 inch FNPTF female thread, allowing direct in-line extension or reconnection of threaded pipe runs. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting during system assembly, repair, or reconfiguration work.

This adapter is suited for use in industrial plumbing, hydraulic, and pneumatic piping systems where NPT threaded connections are standard. The steel construction provides durability in environments with elevated pressure or mechanical stress. It is a practical choice for both new installation and field repair work in commercial and industrial settings where reliable threaded pipe joints are required.

Key Features

• Steel construction for durability in high-pressure service
• 2500 psi pressure rating suitable for demanding fluid and pneumatic applications
• 1-1/4 inch MNPTF male thread by 1-1/4 inch FNPTF female thread configuration
• In-line adapter design for direct pipe extension or reconnection
• Standard NPT thread form for broad system compatibility

Compatibility

Designed as an OEM-style replacement or add-on fitting for industrial and commercial piping systems using 1-1/4 inch NPT threaded connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable local plumbing codes and ASME B1.20.1 thread standards. Depressurize and isolate the piping system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-torque steel NPT fittings, as this can damage threads or cause joint failure.
