Eaton 2045-16-16S Pipe Adapter 1-11-1/2 Mnpt X Fnpsm

Product Description

The EATON 2045-16-16S is a straight pipe adapter designed to connect male NPT threaded pipe to female NPSM threaded fittings in industrial and trade piping systems. Built from steel, it handles a maximum working pressure of 2500 psi and a temperature range from -40 degrees F to 250 degrees F. This adapter provides a reliable transition between MNPT and FNPSM thread forms in hydraulic, pneumatic, and high-pressure fluid systems. It is sized at 1-11-1/2 on both the male and female ends, making it a direct, same-size thread-form conversion fitting. Plumbers, pipefitters, and hydraulic system technicians install this part in both industrial and commercial applications.

This adapter is suited for industrial piping installations where a transition from a standard NPT male thread to an NPSM female thread is required. It is appropriate for high-pressure hydraulic lines, fluid power systems, and heavy-duty plumbing assemblies that require a straight, inline adapter with consistent 1-11-1/2 thread sizing on both ends. The steel construction makes it a practical choice for demanding environments where durability and pressure integrity are critical factors in system design.

Key Features

• Straight adapter configuration with matching 1-11-1/2 thread size on both ends
• MNPT x FNPSM connection type for thread-form conversion in a single fitting
• 2500 psi maximum working pressure rating
• Operating temperature range of -40 degrees F to 250 degrees F
• Steel construction for durability in high-pressure fluid and hydraulic systems
• Meets SAE 140130 standard

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial piping systems requiring a 1-11-1/2 MNPT to FNPSM straight adapter in steel construction.

Installation Notes

This fitting is typically installed by licensed pipefitters or hydraulic system technicians. De-pressurize and isolate the line completely before removing or installing any threaded adapter. Apply appropriate thread sealant compatible with the system fluid and pressure rating. Verify thread engagement and torque to fitting manufacturer guidelines using calibrated hand tools before returning the system to service.
