DANFOSS / EATON ADP O RING F/BOSS FIT

Description & Features

Designed for use with #20 Boss O-ring face seal connections, the Danfoss / Eaton Adp O Ring F/Boss Fit is a hydraulic fitting adapter supplied by Eaton Aeroquip. Boss-style fittings rely on a precisely dimensioned O-ring to achieve a leak-free static seal at the port face, making the condition and correct sizing of this component critical to reliable system performance.

Sourced directly from Eaton Aeroquip, this adapter O-ring is sized for #20 Boss port configurations and is suitable for use in hydraulic circuits where Boss thread fittings are specified. It is compatible with a range of Danfoss and Eaton hydraulic components that use this connection standard.

got an old Eaton boss fitting that needs a new o-ring, this the right one for a #20 size?

Answer by: Customer Support on Dec 18, 2025, 8:09 AM

For a #20 BOSS fitting in the Eaton Aeroquip lineup, yes, this is the correct o-ring. The part number 22617-20 is specifically matched to that size and fitting type, so if you're working with a standard Eaton #20 BOSS port, you're in the right place.
