Parker PT-00040 Pipe Adapter 1/8 Male 1/2 Female Mnptf Fnptf

Product Description

The PARKER PT-00040 is a steel threaded pipe adapter designed to transition between a 1/8 inch male NPT fitting (MNPTF) and a 1/2 inch female NPT fitting (FNPTF). It is rated to 5000 psi, making it suitable for high-pressure hydraulic and pneumatic plumbing applications. The adapter is manufactured from steel for durability in industrial service environments. Licensed plumbers, pipefitters, and industrial maintenance technicians typically install this fitting when connecting lines of different thread sizes within pressurized fluid or gas systems.

This adapter fits into industrial piping systems where a 1/8 inch male NPT thread must mate with a 1/2 inch female NPT port. Common applications include hydraulic power units, compressed air manifolds, and fluid transfer systems in commercial and industrial settings. The MNPTF x FNPTF configuration allows direct thread-to-thread engagement without additional fittings or adapters in the assembly.

Key Features

• 5000 psi pressure rating suitable for high-pressure hydraulic and pneumatic service
• Steel construction for strength and resistance to mechanical stress
• 1/8 inch MNPTF male thread to 1/2 inch FNPTF female thread configuration
• Standard NPT thread form ensures broad compatibility with NPT-ported components
• Sold in a package quantity of 5 units per order

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial piping systems requiring a 1/8 inch MNPTF to 1/2 inch FNPTF threaded adapter in steel.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified industrial maintenance personnel. Depressurize and isolate the system completely before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to the male NPT threads per the system fluid and pressure requirements. Verify torque and leak-free seal before returning the system to service.
