6600 Series back-up rings are precision-engineered components that enhance sealing performance in high-pressure hydraulic systems by preventing O-ring extrusion and maintaining seal integrity. Designed specifically for use with 6600 Series quick couplings, these durable rings provide added support in dynamic applications, helping to extend the lifespan of the primary seals and ensure reliable operation under extreme pressure and temperature fluctuations.
