Designed as a genuine spare part for Vickers by Danfoss/Eaton hydraulic equipment, this Back Up Ring is used alongside O-rings to prevent extrusion under pressure in hydraulic assemblies. Back up rings reinforce the primary seal, extending service life in high-pressure or dynamic sealing applications where O-ring deformation is a concern.
The Vickers Back Up Ring is available in a variety of sizes to suit different bore and gland configurations across compatible Vickers hydraulic components. As an O-rings and gaskets category part, it is suited for use during routine maintenance, seal kit replacements, and equipment rebuilds on Vickers-branded hydraulic cylinders, valves, and pumps.

Question by: Sheila L on Mar 24, 2026, 2:43 PM
What's the deal with this backup ring, what exactly does it do?
Answer by: Customer Support on Mar 26, 2026, 10:50 AM
Functionally, the back up ring reinforces your primary O-ring. It's there to prevent the O-ring from squeezing out of place when things get pressurized, so your seal lasts longer.
