Suspension O-ring 4x1.5 NBR70 for KTM/Husqvarna/GasGas 2002-2026 - 50180222

This genuine OEM O-ring is a critical sealing component designed for high-performance motorcycle suspension systems. Measuring 4x1.5mm and manufactured from durable NBR70 nitrile rubber, it ensures a leak-free seal within front forks and rear shock absorbers. Using original parts maintains the integrity and damping consistency of your WP suspension components.

This versatile part fits an extensive range of models from 2002 to 2026. It is compatible with KTM SX, SX-F, EXC, EXC-F, XC, and XC-W models (125cc to 530cc), as well as Husqvarna FC, FE, TC, and TE series. It also fits GasGas MC and EX models, including specialized Factory, Rockstar, and Heritage editions.

The NBR70 construction provides excellent resistance to suspension fluids, heat, and friction. Its precise dimensions are engineered to withstand the high-pressure environment of off-road racing and trail riding. Replacing worn seals during regular maintenance prevents oil leaks and air contamination that can degrade handling.

We recommend inspecting all O-rings during every suspension service or rebuild. Proper lubrication with suspension-specific grease during installation will help prevent tearing and ensure a long-lasting seal. Always verify the specific requirements of your fork or shock assembly before installation.
