Description
Description
This genuine OEM copper sealing ring (CU sealing ring) is designed to provide a reliable, leak-proof seal within the cylinder head assembly. It is a critical component used to prevent coolant leaks and maintain engine compression by sealing the interface between the cylinder head and its mounting fasteners.
This part features extensive compatibility across KTM, Husqvarna, and GasGas 2-stroke models from 1994 to 2026. It fits KTM 250, 300, and 380 SX, EXC, XC, and XC-W models; Husqvarna TC, TE, and TX 250/300 series; and GasGas EC, EX, and MC 250/300 models, including specialized Six Days and Erzbergrodeo editions.
Manufactured from high-quality copper, this washer is designed to crush slightly upon installation to conform to the mating surfaces. This ensures a perfect seal that can withstand the high temperatures and pressures found in high-performance 2-stroke engines.
Because these are crush-style washers, it is highly recommended to replace them every time the cylinder head is removed or the bolts are loosened. Reusing old washers can lead to cooling system leaks or loss of cylinder pressure, which can negatively impact engine performance.
