Silca Pump Elastomer Seal 252 for Disc Chuck

Description
After more than 20 years on the market the classic SILCA 25.1 gasket has been replaced with the Elastomer #252 Seal which utilises a high tech, fully synthetic Elastomer base material rather than the black carbon-filled natural rubber of previous gaskets. With a life expectancy of more than 5 times the carbon-filled rubber or Buna-N materials used previously this unique, bright-red gasket boasts a blow-off pressure of 393 psi where other designs were unable to reach 120psi.
NOTE: This product is compatible with all previous SILCA disc adapter designs, however, the limited height in the adapter head will prevent the valve stem from fully engaging the gasket. Generally the 252 gasket in a CP1 will hold a minimum 120psi on any size or type of valve stem, while it will hold 70-80psi when used in older SILCA adapters.
