Clutch Slave Cylinder O-Ring for KTM 65/85 SX 2013-2026 - 0770031018

This O-ring (31.47x1.78 mm) is a genuine OEM replacement part designed for the clutch control system. It provides a critical seal for the clutch slave cylinder, preventing hydraulic fluid leaks and ensuring consistent clutch performance.

Compatible with KTM 65 SX (2014-2026), 85 SX (2013-2026), and Freeride 250 R (2014-2017). It also fits Husqvarna TC 65 (2017-2026), TC 85 (2014-2026), and GasGas MC 65 and MC 85 models from 2021-2026, including both 17/14 and 19/16 wheel configurations.

Made from high-quality elastomer material, this O-ring is specifically engineered to resist heat and hydraulic fluids. Replacing worn seals is essential for maintaining proper pressure within the clutch system and preventing air from entering the lines.

During installation, ensure the surfaces are clean and lightly lubricate the O-ring with compatible clutch fluid to prevent tearing. Regular inspection of the clutch slave cylinder for leaks can prevent unexpected failure on the track or trail.
