Eaton 4SA20FRB20-BG Female Ors Swivel 90 Elbow 20 Mm

Product Description

The EATON 4SA20FRB20-BG is a female ORS swivel 90-degree elbow hydraulic hose fitting designed for use in high-pressure hydraulic systems. It connects a 20 mm hose to a fixed port using an O-Ring Face Seal (ORS) interface, which provides a leak-resistant metal-to-metal seat backed by an O-ring. The fitting body is constructed of steel for durability under hydraulic pressure cycling. The swivel design allows the hose to be positioned and torqued to the port without twisting the hose assembly. Thread size is 1-11/16-12, and the hose diameter is 1-1/16 inches. Hex size is 1-7/8 inches. This fitting is installed by hydraulic system technicians, mobile equipment mechanics, and industrial maintenance personnel.

This fitting is suited for mobile hydraulic equipment, industrial machinery, and heavy-duty fluid power systems where a 90-degree change in hose routing is required at a port connection. The ORS swivel configuration is commonly used in agricultural equipment, construction machinery, material handling systems, and similar applications where secure, vibration-resistant connections are critical. Hose size 20 corresponds to the nominal hose bore, and the 1-11/16-12 thread mates with standard ORS port fittings of the same size.

Key Features

• Female ORS swivel interface provides a leak-resistant O-ring face seal connection
• 90-degree elbow geometry allows hose routing changes directly at the port
• Swivel design prevents hose twisting during installation and torquing
• Steel construction suited for high-pressure hydraulic service
• Thread size 1-11/16-12 mates with standard ORS ports of the same designation
• 1-7/8 inch hex size for use with standard open-end or combination wrenches

Compatibility

Designed as an OEM-style replacement hydraulic hose fitting for systems using 20 mm hose with 1-11/16-12 female ORS swivel port connections.

Installation Notes

Installation is performed by qualified hydraulic system technicians or industrial mechanics. De-pressurize and bleed down the hydraulic system fully before disconnecting any lines or fittings. Inspect the O-ring sealing face and the O-ring itself for damage before assembly. Tighten to the fitting manufacturer's specified torque using the correct size wrench on the hex; do not use the hose or hose end as a lever.
