Key Features
- OEM-Grade Sealing Material — manufactured to Husqvarna's compound and compression specifications, delivering the correct elasticity and chemical resistance required for floor grinder service environments.
- Exact-Profile Replacement — matches the original cross-section and diameter precisely, seating cleanly into the groove without adjustment or trimming.
- Broad Floor Grinder Compatibility — fits a wide range of Husqvarna PG, DURATIQ, and HTC floor grinders, including the PG830 series, PG8 variants, DuratiqT8, DURATIQX8, HTCT8, HTCX8, and HTCRX8 models.
- Leak Prevention — a correctly seated O-Ring maintains fluid or air containment within the assembly; a worn or damaged ring allows seepage that can degrade surrounding components and compromise machine operation.
- Fluid System Integrity — on floor grinding equipment, sealing components in hydraulic and lubrication circuits are critical to consistent motor output and safe, controlled operation; using the correct OEM-spec ring supports proper system pressure.
An O-Ring is a precision-molded loop of elastomeric material that forms a pressure-tight seal between two mating surfaces or within a groove in a housing. In floor grinders like the PG830 and DURATIQ series, O-Rings are used throughout hydraulic circuits, drive assemblies, and fluid passages to prevent leaks and maintain internal pressure. When an O-Ring deteriorates — through heat cycling, chemical exposure, or simple age — it loses its ability to compress and seal, leading to fluid loss, pressure drop, and potential damage to the components it protects.
