Key Features
- OEM-Grade Seal Material — manufactured to Husqvarna's exact compound and hardness specification, ensuring correct compression and resistance to the fluids and pressures found in PG, DURATIQ, and HTC floor grinders
- Drop-In Replacement Fit — dimensioned to seat precisely in the original groove without trimming or adaptation, making installation straightforward during scheduled service or field repair
- Broad Floor Grinder Compatibility — fits an extensive range of Husqvarna floor grinder models across the PG, HTC, and DURATIQ families, including the PG510, PG540, PG690, PG830, DuratiqT5, DuratiqT6, DuratiqT8, DuratiqX6, DuratiqX8, HTCXP6, HTCT5, HTCT8, HTCX8, HTCRX8, HTC510, and additional variants
- Leak Prevention — a correctly seated O-Ring maintains fluid or pressure containment within the assembly; a worn or damaged ring allows leaks that can lead to contamination, loss of lubrication, and progressive internal damage
- Genuine Husqvarna Part — supplied as a factory OEM component, ensuring the seal meets the original design intent for the machines it serves rather than relying on an approximated aftermarket fit
An O-Ring is a circular elastomeric seal that sits within a machined groove and compresses between mating surfaces to prevent fluid, air, or contaminant ingress. In floor grinders, O-Rings are used throughout drive assemblies, gear housings, and fluid circuits where a reliable, low-profile seal is required. When an O-Ring ages, it loses elasticity, develops cracks, or takes a permanent set — allowing fluids to leak past the seal and contaminants to enter critical internal components. Replacing a failed O-Ring promptly with a correctly specified part restores the integrity of the sealed assembly and prevents more costly secondary damage.
