The Multiquip H5BUR50403 Back Up Ring HBC-25 is a genuine OEM component designed for the HBC-25. As a factory-sourced part, it is manufactured to the exact material and dimensional standards required for proper sealing performance in your equipment. This is the correct replacement ring for HBC-25 applications, ensuring a direct, secure fit within the sealing assembly it supports.
Key Features
- OEM Sealing Material Grade — Produced to the precise compound and hardness specifications required for this sealing application, maintaining compression integrity over repeated operating cycles.
- Exact-Fit Replacement — Dimensioned to seat correctly within the HBC-25 sealing groove without trimming or reworking the mating surfaces.
- Confirmed HBC-25 Fitment — Sourced specifically for HBC-25 equipment; use part number H5BUR50403 to verify compatibility before ordering.
- Prevents Seal Extrusion — A correctly installed back up ring supports the primary seal under pressure, preventing it from extruding into the clearance gap and extending the life of the overall seal assembly.
- Genuine Multiquip OEM Part — Supplied direct from the Multiquip parts chain, so you receive the same component installed at the production stage.
A back up ring works alongside a primary O-ring or hydraulic seal to prevent that seal from being forced into the clearance gap between mating components when system pressure is applied. Without it, the primary seal deforms prematurely, leading to fluid bypass, pressure loss, and accelerated wear on surrounding components. Replacing a worn or damaged back up ring restores the integrity of the entire sealing assembly and keeps the system operating at its designed pressure range.
