Eaton 2045-2-2S Pipe Adapter 1/8-27 Mnpt X Fnpsm Steel

Product Description

The EATON 2045-2-2S is a straight pipe adapter designed for industrial fluid and pneumatic systems requiring a transition between male NPT and female NPSM threads, both sized at 1/8-27. Constructed from steel, this adapter is rated for a maximum working pressure of 5,000 psi and handles temperatures ranging from -40 degrees F to 250 degrees F. It is a compact, single-piece fitting that provides a reliable, leak-resistant connection in high-pressure hydraulic and pneumatic lines. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of adapter where thread-form conversion is needed at a port or inline connection point.

This adapter is suited for use in industrial machinery, hydraulic power units, pneumatic control systems, and other applications where 1/8-27 threaded ports are present. The MNPT x FNPSM connection type accommodates the slight thread-form difference between tapered NPT and straight NPSM female ports, making it a practical solution in both OEM assembly and field service scenarios. It is appropriate for residential and light commercial applications as well, wherever 1/8-inch ported components require a secure, pressure-rated mechanical connection.

Key Features

• Steel construction for strength and durability in high-pressure hydraulic and pneumatic service
• 5,000 psi maximum working pressure rating for demanding system applications
• Wide temperature range: -40 degrees F to 250 degrees F
• Straight fitting shape for direct inline or port-to-port installation
• MNPT x FNPSM thread configuration handles tapered-to-straight thread transitions at 1/8-27
• Meets SAE 140130 standard

Compatibility

Designed as an OEM-style replacement or field-service fitting for industrial hydraulic and pneumatic systems using 1/8-27 male NPT and female NPSM threaded ports.

Installation Notes

Installation is typically performed by licensed pipefitters, plumbers, or industrial maintenance technicians. Depressurize and isolate the system completely before removing or installing any fittings. Apply appropriate thread sealant to the male NPT threads per system fluid compatibility requirements; NPSM straight threads may require an O-ring or gasket seal depending on the mating port design. Follow applicable codes and the equipment manufacturer's torque and assembly guidelines when securing the fitting.
