Traditional silica 24.1 gaskets have been on the market for over 20 years, but this new 242 gasket is specially synthesized rather than simply black in color compared to previous natural rubber. It is very red due to the use of elastomer material. This unique bright red gasket borrows wisdom from the industry, which requires airtightness even in the harshest environments. And its lifespan is more than five times longer than the materials used so far, such as rubber and Buna-N.
The new two-stage construction ensures confidentiality to both the valve stem and valve core thread base and also helps improve durability. It slides into the valve stem with a satisfying click, and its unique internal shape uses air pressure to compress the gasket into the valve stem. In other words, the more you pump, the more firmly you hold the valve.
Note: This gasket is only compatible with 30.0 / 30.2 and 17-4 stainless steel presta valve heads and similar constructions.
