Parker PT-00046 Pipe Adapter Mnptf X Fnptf Steel 4000 Psi

Product Description

The PARKER PT-00046 is a steel pipe thread adapter designed to connect 1/2 inch male NPT threads to 3/4 inch female NPT threads in industrial fluid and pneumatic piping systems. It uses an MNPTF x FNPTF configuration, providing a tapered thread-to-tapered thread seal suitable for high-pressure service. With a maximum working pressure of 4,000 psi, this adapter is built for demanding hydraulic and industrial plumbing applications. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting when transitioning between two different NPT thread sizes in a run of pipe or tubing.

This adapter is suited for use in industrial facilities, manufacturing plants, hydraulic power units, and commercial plumbing systems where 1/2 inch to 3/4 inch NPT size reductions or expansions are required. Its steel construction handles the mechanical stress and pressure demands common in these environments. It ships in a package quantity of two units per order.

Key Features

• 1/2 inch male NPT to 3/4 inch female NPT thread configuration
• MNPTF x FNPTF tapered thread connection type
• 4,000 psi maximum working pressure rating

• Sold in packages of two units

Compatibility

Designed as an OEM-style replacement or drop-in addition for industrial piping systems requiring a 1/2 inch MNPTF to 3/4 inch FNPTF threaded pipe adapter at up to 4,000 psi working pressure.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Depressurize and isolate the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads in accordance with the applicable piping code before assembly. Do not overtighten tapered NPT threads, as this can crack fittings or distort sealing surfaces.
