Eaton 2070-8-8S Steel Swivel Nut 45 Elbow 1/2 in Tube Od

Product Description

The EATON 2070-8-8S is a steel 45-degree swivel nut elbow fitting designed for flared tube connections in hydraulic and fluid-transfer systems. It features a flare-by-swivel end configuration with a 37-degree flare angle and a 3/4-16 SAE thread size. Rated to 4000 psi maximum working pressure, this fitting handles service temperatures ranging from -65 degrees F to 400 degrees F. The swivel nut design allows the nut end to rotate freely during installation, reducing torque transfer to the tube and making alignment significantly easier in tight spaces. Installers in hydraulic, refrigeration, and industrial plumbing applications rely on this fitting where a fixed elbow would be impractical.

The 2070-8-8S is suited for use in hydraulic lines, fluid power circuits, and high-pressure tubing assemblies where a 45-degree directional change is required. It accepts 1/2-inch OD flared tubing on the flare end and connects via a 3/4-16 SAE swivel nut on the other end. Common applications include mobile equipment hydraulics, machine tool fluid lines, and industrial equipment where SAE 37-degree flared connections are the specified standard. This fitting meets SAE 070321 standards.

Key Features

• 45-degree elbow configuration for directional routing in confined or angled runs
• 37-degree SAE flare angle meets SAE 070321 standard
• Swivel nut end rotates freely to ease alignment and reduce tube stress during makeup
• Rated to 4000 psi maximum working pressure
• Operating temperature range: -65 degrees F to 400 degrees F
• Steel construction for durability in high-pressure fluid power applications

Compatibility

Designed as an OEM-style SAE 37-degree flared tube fitting for use with 1/2-inch OD tubing and 3/4-16 SAE threaded ports in hydraulic and fluid-transfer systems conforming to SAE standards.

Installation Notes

Installation is typically performed by hydraulic system technicians or licensed pipefitters. Depressurize and drain the system completely before removing or installing any hydraulic fittings. Use a backup wrench on the fitting body when tightening the swivel nut to prevent tube windup or body rotation. Verify flare quality and seat condition before makeup, as a damaged or out-of-spec flare will compromise the rated working pressure of the connection.
