Eaton 2045-6-8S Pipe Adapter Mnpt X Fnpsm Steel 2500 Psi

Product Description

The EATON 2045-6-8S is a straight steel pipe adapter designed to connect a 1/2-14 MNPT male thread to a 3/8-18 FNPSM female thread in hydraulic and industrial piping systems. This fitting allows technicians to transition between two common NPT thread sizes in a single inline connection. It carries a maximum working pressure of 2,500 psi and handles temperatures from -40 degrees F to 250 degrees F, making it suitable for a wide range of fluid power and industrial plumbing applications. Steel construction provides durability under high-pressure service conditions.

This adapter is used in industrial fluid power systems, hydraulic circuits, and high-pressure plumbing assemblies where a size transition between 1/2-inch and 3/8-inch pipe threads is required. It is appropriate for both stationary and mobile equipment installations. Plumbers, pipefitters, and hydraulic system technicians routinely install this type of fitting when adapting between mismatched port sizes on pumps, valves, manifolds, and inline components.

• Steel construction for high-pressure and industrial environments
• Meets SAE 140130 standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial and hydraulic piping systems requiring a straight MNPT x FNPSM adapter between 1/2-14 and 3/8-18 pipe thread sizes.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or qualified hydraulic system technicians. Depressurize and isolate the system completely before removing or installing any fittings. Apply appropriate thread sealant or PTFE tape to the male threads per the system fluid compatibility requirements. Torque the fitting using proper pipe wrenches to avoid thread damage or distortion of connected components.
