The Reusable Seals Kit 86726734 is optimized for key component sealing in HC25 Hydraulic Rock Drills, focusing on high-wear areas like cylinders and pistons. Generic seals kits for these components have inconsistent quality, with some seals failing within 300-400 hours. This OEM kit uses premium rubber compounds that offer 50% longer service life than generic seals, with specific formulations tailored to each component’s operating conditions (e.g., high-pressure for cylinders, dust-resistance for pistons). It includes extra seals for critical locations, reducing the need for emergency replacements, and requires mandatory replacement after 800 hours to maintain system integrity.
