Key Features
- OEM Material Integrity — Manufactured to Multiquip's original sealing specifications, ensuring correct compression behavior and chemical resistance for the application.
- Drop-In Installation — Dimensioned to seat exactly as the original, with no reworking of mating surfaces or hardware required during installation.
- Broad Confirmed Fitment — Compatible with MVH502DSB2, MVH502DSB, MQ41TDH, and MDR-9D models, spanning reversible plate compactors, trash pumps, and power trowels.
- Leak Prevention — A correctly seated sealing ring maintains fluid containment and system pressure, preventing leaks that can lead to component wear or fluid contamination.
- Fluid System Safety — In fuel and hydraulic circuit applications, a compromised sealing ring can create fire or pressure hazards; using the correct OEM-spec ring is essential for safe operation.
A sealing ring creates a compression-based barrier between mating components, preventing fluid, oil, or air from escaping a pressurized system or joint. When installed correctly, it maintains the integrity of the surrounding assembly by filling the gap between two surfaces under load. When a sealing ring wears, hardens, or becomes damaged, the result is leakage, pressure loss, or contamination of adjacent components — any of which can cause accelerated wear or equipment failure if left unaddressed.
