Eaton 90° Elbow Fitting 1/4" Hose

This Eaton 1AA4FRB4 is a 90 degree elbow fitting designed for hydraulic hose assemblies. It connects a 1/4 inch inner diameter hose to a female ORS port with 9/16-18 thread size. The crimpable connection type creates a permanent seal for fluid power systems. It suits technicians building or repairing hydraulic lines in mobile or industrial equipment.

Verify hose dash size and thread compatibility

Before ordering confirm the hose dash size matches dash size 4 for 1/4 inch I.D. hose. Ensure the mating port uses a female ORS 9/16-18 thread to match this fitting. Check that the crimpable connection method aligns with your assembly equipment and process. The fitting meets SAE 100R1 and SAE 100R2 standards for dimensional reference.

Steel construction with trivalent chromium zinc

The steel body resists deformation under sustained system pressure during continuous operation. The ROHS compliant trivalent chromium zinc finish protects against corrosion in harsh environments over extended periods. GH793 standards compliance indicates suitability for demanding hydraulic applications. The 2.09 inch length provides a compact profile for tight routing under load.

Questions about this item

What comes with the Eaton 1AA4FRB4 elbow fitting and is any extra hardware required?

The package contains the single steel elbow fitting with a 90 degree bend, 9/16-18 female ORS thread and 1/4 inch hose barb. Crimp ferrules and compatible hose are not included and must be sourced separately.

Which version of the 1AA4FRB4 should I select for a 1/4 inch hose with ORS connection?

This model is the only version listed; it matches a 1/4 inch hose I.D., dash size 4, and 9/16-18 female ORS thread. No alternative capacities or thread options are offered for this part number.

What does the 90 degree elbow angle mean when the fitting is installed in a hydraulic line?

The 90 degree bend redirects flow at a right angle, allowing the hose to run perpendicular to the port. Overall length is 2.09 inches, and the fitting meets SAE 100R1, SAE 100R2 and GH793 standards for crimpable connections.
