Eaton 2045-4-4S Pipe Adapter 1/4-18 Mnpt X Fnpsm Steel

Product Description

The EATON 2045-4-4S is a straight industrial pipe adapter designed to connect male NPT threads to female NPSM threads in high-pressure hydraulic and pneumatic plumbing systems. It features a 1/4-18 male NPT connection on one end and a 1/4-18 female NPSM connection on the other, built from steel for durability in demanding service environments. The adapter is rated for a maximum working pressure of 5000 psi and handles temperatures from -40 degrees F to 250 degrees F. It is installed by licensed plumbers, hydraulic technicians, and pipefitters working on industrial fluid and pressure lines.

This adapter suits industrial plumbing and hydraulic applications where an MNPT-to-FNPSM transition is required in a straight-through configuration. Its compact straight design makes it suitable for tight installation spaces. The SAE 140130 standard rating ensures it meets recognized industry requirements for threaded pipe fittings used in fluid power and general industrial piping systems.

Key Features

• Straight adapter configuration for direct MNPT to FNPSM thread transitions
• 1/4-18 male NPT and 1/4-18 female NPSM thread sizes on each end
• Maximum working pressure of 5000 psi for high-pressure service
• Operating temperature range of -40 degrees F to 250 degrees F

Compatibility

Designed for use in industrial pipe and hydraulic systems requiring a 1/4-18 MNPT x FNPSM straight adapter connection in steel construction.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or hydraulic technician. Depressurize and isolate the line completely before removing any existing fittings or installing this adapter. Apply appropriate thread sealant compatible with the system fluid and pressure rating. Follow applicable codes including IFGC or IPC as relevant to the installation environment.
