Husqvarna 505103501 O-Ring 10.5x2.7 EPDM

Replacement seal for Husqvarna concrete saws that maintains hydraulic and cooling system integrity during extended cutting operations. This EPDM O-ring measures 10.5mm inner diameter by 2.7mm cross-section, providing chemical resistance against fuel, oil, and water exposure common on job sites. EPDM material withstands temperature fluctuations and UV exposure better than standard rubber seals, reducing downtime from equipment failures. Prevents coolant leaks and maintains proper pressure in saw components during heavy-duty cutting applications. Direct OEM replacement part ensures exact fitment without modification. Keep spares in your service kit to avoid delays when seals wear out during multi-day pours or demolition work. Built for concrete contractors, rental operations, and maintenance crews servicing Husqvarna cutting equipment in the field.
