Eaton 2045-12-12S Pipe Adapter 3/4-14 Mnpt X Fnpsm Steel

Product Description

The EATON 2045-12-12S is a straight steel pipe adapter designed to connect a 3/4-14 male NPT thread to a 3/4-14 female NPSM thread. It converts between standard tapered pipe threads and straight mechanical threads in a single inline fitting. Rated to 2500 psi working pressure, it handles a wide temperature range from -40 degrees F to 250 degrees F, making it suitable for hydraulic, pneumatic, and fluid transfer lines in industrial and commercial applications. Licensed plumbers, pipefitters, and hydraulic technicians are the primary installers. The fitting ships as a single unit and meets SAE 140130 standards.

This adapter is used in industrial piping and fluid power assemblies where a tapered NPT male connection must mate with a straight NPSM female port. Typical applications include hydraulic manifolds, compressor lines, and fluid distribution systems in both shop and field service environments. The straight fitting shape allows for direct inline installation without directional offset, simplifying routing in tight spaces.

Key Features

• Straight adapter configuration for inline MNPT to FNPSM conversion
• 2500 psi maximum working pressure for demanding fluid power service
• Operating temperature range: -40 degrees F to 250 degrees F
• Steel construction for durability in industrial environments
• Meets SAE 140130 standard
• 3/4-14 thread size on both male and female ends

Compatibility

Designed as a standard inline adapter for industrial piping and fluid power systems requiring a 3/4-14 MNPT x FNPSM thread conversion in a straight configuration.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or hydraulic technician. Depressurize and isolate the line completely before removing or installing any fitting. Apply appropriate thread sealant to the tapered NPT male threads per the system fluid compatibility requirements. Do not overtighten; use a calibrated torque wrench and follow the system manufacturer or applicable code guidelines for thread engagement.
