OEM Water Pump & Cylinder Head O-Ring 9x1.5mm for KTM & Husqvarna - 07700900151

This genuine OEM O-ring (9x1.5mm) is a critical sealing component designed for high-performance motorcycle engines. It is primarily used in water pump assemblies and cylinder head configurations to prevent leaks and maintain optimal pressure. As an original part, it ensures a perfect fit and reliable performance under extreme heat and pressure.

This versatile seal is compatible with an extensive range of models including the KTM 1390 Super Adventure S/R, 1290 Super Duke R/GT, 990 Duke, 890 Adventure, and 790 Duke. It also fits off-road models like the KTM 250, 350, 450, and 530 EXC-F and SX-F series, Husqvarna FE 250/350, FC 250/350, 701 Enduro/Supermoto, and Norden 901, as well as GasGas EC, MC, and EX series.

Constructed from high-quality V80 Viton material, this O-ring offers superior resistance to chemicals, oils, and high temperatures. Its precise 9x1.5mm dimensions provide a secure seal for cooling systems and engine internals. Replacing worn O-rings during routine maintenance is essential to prevent coolant loss or oil contamination.

When installing, ensure the seating surface is clean and free of debris to prevent premature failure. Applying a light coat of compatible lubricant can help the O-ring seat correctly without pinching. This small but vital component is a cost-effective way to protect your engine from potential damage caused by fluid leaks.
