Description
Description
This 64x2 FPM O-ring is a critical sealing component for the cylinder head assembly. As an authentic OEM part, it is designed to maintain a high-pressure seal between the cylinder and the head, preventing coolant leaks and compression loss during operation.
Compatible with a wide range of 150cc models including KTM 150 SX (2016-2025), 150 EXC/TPI (2020-2023), and 150 XC-W/TPI (2017-2023). It also fits Husqvarna TC 150 (2025), TE 150/i (2017-2023), and the GasGas MC 150 (2025).
Constructed from high-quality FPM (Viton) with an 80 Shore hardness rating, this ring offers superior resistance to extreme heat and engine chemicals. Its precise dimensions ensure a perfect fit for reliable engine performance under demanding racing conditions.
When performing a top-end rebuild, it is highly recommended to replace all seals to ensure engine integrity. Always lubricate the O-ring slightly before installation to prevent pinching or tearing during the assembly process.
