Eaton 2070-6-6S Steel 45 Deg Swivel Nut Elbow 3/8 in Od

Product Description

The EATON 2070-6-6S is a steel 45-degree swivel nut elbow fitting designed for flared tube connections in hydraulic and fluid power plumbing systems. It features a flare-by-swivel end configuration with a 37-degree flare angle and a 9/16-18 SAE thread. The fitting has a 3/8-inch tube outside diameter and a 0.40-inch inside diameter, with an overall length of 1.57 inches. Rated to 4000 psi maximum working pressure, it handles temperatures from -65 degrees F to 400 degrees F. Licensed HVAC technicians, plumbers, and fluid power mechanics install this type of fitting in compressed air, refrigeration, and hydraulic line assemblies.

This fitting is suited for residential and commercial fluid system installations where a 45-degree directional change in a flared tube line is required. The swivel nut design allows the fitting body to be positioned and the nut to be tightened independently, simplifying alignment in tight spaces. Typical applications include hydraulic control circuits, pneumatic distribution lines, and refrigerant piping where SAE flare connections are specified. Its steel construction and 4000 psi pressure rating make it appropriate for moderate- to high-pressure service lines.

Key Features

• 45-degree elbow geometry with 37-degree SAE flare angle for directional routing in confined installations
• Swivel nut end allows independent rotation during installation, reducing torque transfer to tubing
• 4000 psi maximum working pressure rating for moderate- to high-pressure fluid systems
• Operating temperature range of -65 degrees F to 400 degrees F covers a wide range of service conditions
• Steel construction provides strength and durability in hydraulic and pneumatic applications
• Meets SAE 070321 standard for dimensional and performance compliance

Compatibility

Designed as an OEM-style replacement or new-installation flare fitting for fluid power, hydraulic, and pneumatic systems requiring a 3/8-inch OD tube connection with a 9/16-18 SAE thread and 37-degree flare angle.

Installation Notes

Installation should be performed by a qualified plumber, hydraulic technician, or HVAC mechanic familiar with SAE flare fittings and applicable system codes. Depressurize and isolate the fluid circuit completely before removing or installing any fitting. Inspect the tube flare for cracks or deformation before assembly, as a compromised flare seat will cause leaks under pressure. Do not over-tighten the swivel nut; follow applicable SAE assembly guidelines for flare-type fittings.
