Designed to be used as a vent or inlet valve for vacuum systems. Can also be used to construct AIRFREE® or Schlenk glassware in place of the standard straight bore glass stopcock. This totally grease-free valve does not require a sidearm since the valve has a bore that runs through the plug and an integral machined-on serrated hose connection for attachment to the vacuum or inert gas source. The primary seal is made on the precision tooled seat with the shaft seal being made with a Chem-Cap® encased o-ring. The bore is 4mm with an 8mm OD hose connection.
