The traditional Silica 24.1 gasket has been on the market for over 20 years, but this new 242 gasket is not simply black in color compared to the previous natural rubber version, but is very red due to the use of a specially synthesized elastomeric material. This unique bright red gasket borrows its wisdom from the industrial world, which requires airtight performance even in the harshest of environments. And compared to previously used materials such as rubber or Buna-N, its lifespan is more than five times longer.
The new two-stage construction ensures tightness to both the valve stem and the valve core thread base, which also plays a role in improving durability. Sliding into the valve stem with a satisfying click, the unique internal geometry uses air pressure to compress the gasket onto the valve stem. In other words, the more you pump, the more firmly it holds the valve in place.
Note: This gasket is only compatible with 30.0 / 30.2 and 17-4 stainless Presta valve heads and similar constructions.
