Eaton 2045-8-6S Pipe Adapter 3/8-18 X 1/2-14 Steel 2500 Psi

Product Description

The EATON 2045-8-6S is a straight pipe thread adapter designed to connect a 3/8-18 male NPT fitting to a 1/2-14 female NPSM thread. It is rated for a maximum working pressure of 2,500 psi and handles temperatures from -40 degrees F to 250 degrees F, making it suitable for demanding hydraulic, pneumatic, and industrial fluid system applications. Constructed from steel, this adapter provides the mechanical strength required in high-pressure plumbing and fluid transfer lines. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers for this type of fitting.

This adapter fits inline installations where a threaded size transition is required between a 3/8-18 MNPT port and a 1/2-14 FNPSM connection point. Common use cases include hydraulic manifolds, compressed air lines, and industrial fluid distribution systems where mixed thread standards are present. The straight body configuration keeps the plumbing path direct with no angular offset. It meets SAE 140130 standards, confirming dimensional and performance compliance for industrial service.

Key Features

• Straight adapter configuration with 3/8-18 MNPT male thread and 1/2-14 FNPSM female thread
• 2,500 psi maximum working pressure rating for high-pressure fluid and pneumatic systems
• Operating temperature range of -40 degrees F to 250 degrees F
• Steel construction for durability in industrial and hydraulic environments
• Meets SAE 140130 standards for dimensional and pressure performance

Compatibility

Designed as an OEM-style replacement or drop-in fitting for industrial fluid systems requiring a 3/8-18 MNPT to 1/2-14 FNPSM straight thread adapter in steel construction.

Installation Notes

Installation is typically performed by licensed pipefitters, plumbers, or qualified industrial maintenance technicians. Depressurize and isolate the system completely before removing or installing any threaded fittings. Apply appropriate thread sealant compatible with the system fluid and pressure rating. Do not overtighten threaded connections; use a calibrated torque wrench and follow system-specific assembly guidelines per applicable codes.
