Precision Silicone Seal for RC Maintenance

The Yokomo YS-7SX silicone O-ring is engineered for steady sealing and extended life in RC assemblies. Its X-shaped section enhances contact under load, helping to prevent oil weep and maintain consistent operation during use.

Practical Advantages for Model Tuning

  • Material Upgrade: Silicone construction increases longevity and maintains elasticity over repeated use.
  • Innovative Design: The X-section gives improved sealing contact and reduces internal friction.
  • Leak Prevention: Built to resist oil escape and preserve performance across sessions.
  • Versatile Application: Suitable across a wide range of RC setups, from practice runs to tight competition tuning.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does the YS-7SX compare to a standard circular O-ring?

The X-shape creates multiple sealing lips that adapt under pressure, offering a more reliable seal and reducing progressive wear seen with simple round sections.

Are these O-rings compatible with silicone and mineral oils?

They are designed to handle common shock oils and light mineral oils used in RC gear; avoid aggressive solvents that can damage silicone over time.

Do I need special tools to fit the YS-7SX?

No special tools are required; fit by hand or with simple plastic picks to avoid nicks, and ensure the groove is clean before seating the ring.

When should I replace these seals?

Replace during any major tear-down or if you notice oil traces, deformation or loss of elasticity to maintain reliable performance.

Can I use the YS-7SX in vintage or retro models?

Yes, the compact design works well in older shock and gearbox layouts where space is limited and a modern seal upgrade is desired.
