The Iconic SILCA 24.1 seal has been updated and improved after more than 30 years in the market. The new 242 seal utilizes a high tech and very red, fully synthetic elastomer base material rather than a carbon black filled natural rubber of previous seals. This unique bright red seal borrows from industries which require air-tight seals in the harshest of environments, and tests to a life expectancy of more than 5X the carbon filled rubber or Buna-N materials used previously.
