Key Features
- Genuine OEM Material Grade — Produced from the same compound and durometer specification as the original, ensuring proper compression and sealing behavior under operating pressures.
- Direct-Fit Installation — Engineered to seat into the same groove geometry as the original ring, allowing a straightforward swap without modification to surrounding components.
- Confirmed HBC-19 Fitment — Verified for use on HBC-19 equipment; use part number H9BUR45353 to match this ring to your specific unit.
- Seal Integrity Under Load — A correctly installed back up ring prevents seal extrusion under pressure, maintaining system integrity and consistent performance across operating cycles.
- Prevents Premature Seal Failure — Replacing a worn or damaged back up ring at the proper service interval protects adjacent seals and reduces the risk of fluid bypass or system pressure loss.
A back up ring works alongside a primary seal to prevent seal extrusion into the clearance gap between mating components when the system is under pressure. Without it, the primary seal can deform, crack, or blow out — leading to fluid leaks, loss of pressure, and potential damage to surrounding components. Replacing a worn back up ring at the right service interval is one of the most cost-effective ways to maintain hydraulic or pneumatic system reliability.
