Key Features
- Genuine OEM Sealing Material — manufactured to Husqvarna's exact elastomer grade and compression rating, delivering the same seal integrity as the original component installed at the factory.
- Exact-Dimension Replacement — matches the original O-Ring's inner diameter, outer diameter, and cross-section precisely, so it seats correctly in the groove without adjustment or trimming.
- Broad Floor Grinder Compatibility — fits PG690, PG690RC, PG6P, PG6S, PG690P, DURATIQT6, DURATIQX6, and HTCXP6 floor grinders, covering both the PG and DURATIQ/HTC premium grinder lines.
- Leak-Free Circuit Integrity — a correctly seated O-Ring maintains pressure and prevents fluid or air bypass; a worn or damaged ring leads to leaks, pressure loss, and unplanned service interruptions.
- Fluid System Safety — using a correctly spec'd OEM O-Ring in hydraulic or coolant circuits prevents seepage that could create slip hazards or contaminate the work surface during grinding operations.
An O-Ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces or within a fluid passage, creating a pressure-tight barrier that prevents liquid or air from escaping the circuit. In a floor grinder, these seals are critical to maintaining the integrity of hydraulic, water feed, or lubrication systems — keeping fluids where they belong so the machine delivers consistent power and cooling to the grinding heads. When an O-Ring hardens, cracks, or is pinched out of its groove, the resulting leak reduces system pressure and can cause overheating, erratic performance, or surface contamination on the floor being processed.
