The Husqvarna 574441304 Plug is a genuine OEM component designed for the PG680, PG820, and PG820RC floor grinders. As a direct OEM replacement sourced through Husqvarna's construction equipment line, this plug is built to the same specifications as the original part installed at the factory. It is engineered to fit correctly within the PG680, PG820, and PG820RC platform, ensuring the machine is restored to proper working order without adaptation. DHS Equipment supplies this part to help keep your floor grinding equipment running at full capacity.
Key Features
- Genuine OEM Construction — manufactured to Husqvarna's exact material and dimensional specifications for a secure, lasting seal and correct function in the grinder's housing or fluid circuit.
- Direct-Fit Replacement — engineered to match the original mounting point, allowing straightforward installation without modification on compatible machines.
- Confirmed Fitment — verified for the PG680, PG820, and PG820RC planetary floor grinders, covering both standard and remote-controlled variants in the PG820 series.
- Maintains System Integrity — a correctly seated plug prevents fluid loss, contamination ingress, or pressure loss in the circuit it closes, keeping the grinder performing as intended.
- Part Number Assurance — cross-reference 574441304 against your Husqvarna parts diagram to confirm the correct position before ordering.
A plug in a floor grinder serves to seal an opening in the machine's housing, fluid system, or drive assembly — blocking ports that are not in active use or closing off service access points after maintenance. When a plug is cracked, missing, or improperly seated, it can allow contaminants such as dust, water, or slurry to enter the machine's internal components, or permit hydraulic and lubrication fluid to escape. Either condition accelerates wear on surrounding components and can lead to more significant mechanical failures over time. Replacing a damaged plug promptly with the correct OEM part restores the sealed environment the machine depends on for consistent, efficient operation.
