Eaton 2045-8-8S Pipe Adapter 1/2-14 Mnpt X Fnpsm Steel

Product Description

The EATON 2045-8-8S is a straight industrial pipe adapter designed to connect male NPT threads to female NPSM threads in hydraulic and fluid-transfer plumbing systems. It features a 1/2-14 male thread on one end and a 1/2-14 female thread on the other, providing a reliable inline transition between MNPT and FNPSM thread types. Constructed from steel, this adapter handles a maximum working pressure of 3000 psi and a pressure rating of 2500 psi, making it suited for demanding industrial and mechanical fluid lines. Licensed plumbers, pipefitters, and hydraulic system technicians install this type of fitting in both stationary and mobile equipment applications.

This adapter is used in industrial piping, hydraulic manifold assemblies, and fluid-power systems where an NPT-to-NPSM thread transition is required. Its straight configuration keeps routing compact in tight installations. The fitting suits applications operating within a temperature range of -40 degrees F to 250 degrees F, covering most standard industrial fluid and hydraulic service conditions. It is sold and packaged as a single unit.

Key Features

• Straight adapter profile for inline MNPT to FNPSM thread transitions
• 1/2-14 male NPT and 1/2-14 female NPSM threads on opposing ends
• Steel construction rated for high-pressure hydraulic and fluid service
• Maximum working pressure of 3000 psi with a pressure rating of 2500 psi
• Operating temperature range from -40 degrees F to 250 degrees F
• Meets SAE 140130 standards

Compatibility

Designed as an OEM-style replacement or service fitting for industrial hydraulic and fluid-transfer piping systems requiring a 1/2-14 MNPT x FNPSM straight adapter connection.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or hydraulic technician. Depressurize and isolate the fluid system completely before removing or installing any fittings. Apply thread sealant appropriate for the fluid media and thread type — NPSM threads are straight and rely on a seat or sealant rather than thread taper for sealing. Verify that system operating pressure does not exceed the rated working pressure of the fitting or any other component in the assembly.
