Red HNBR O-Ring 5.28x1.78 for KTM Husqvarna GasGas 2002-2026 - S208600003000FB

This genuine OEM red O-ring is a high-quality sealing component designed for precision performance in motorcycle systems. Measuring 5.28x1.78mm and manufactured from HNBR70 (Hydrogenated Nitrile Butadiene Rubber), this part is engineered to withstand extreme heat and chemical exposure. It serves as a critical seal in various assemblies, including shock absorbers and evaporative canister systems, ensuring airtight and leak-proof operation.

This O-ring features an incredibly broad compatibility range across KTM, Husqvarna, and GasGas motorcycles from 2002 to 2026. It fits everything from small-displacement motocross bikes like the 50 SX and TC 50 to flagship models such as the 1390 Super Duke R and 1290 Super Adventure. It is also compatible with the full range of EXC, FE, EC, and XC enduro and dual-sport models, making it a versatile staple for any maintenance kit.

The use of HNBR70 material provides superior durability compared to standard rubber, offering better resistance to oils, fuels, and high-temperature environments. Using original factory parts ensures that the seal maintains its integrity under the high-pressure conditions found in modern suspension and fuel systems. Replacing these seals during routine service is essential for preventing fluid loss and maintaining optimal performance.
