•  Dur-O-Seal is an alternative sealing mechanism to the standard 
   metal-to-metal Techlok sealring.
-------------------------------------------------------------------------------------------
•  It is used to maximum advantage where seats are badly
   corroded or damaged, or in sandy conditions on service
   and vessel closures/pig launchers where repeated make-breaks
   are required.
-------------------------------------------------------------------------------------------
•  Dur-O-Seal is fully interchangeable with all clamp connectors.
   It utilises standard, easily replaceable '0' rings, and eliminates
   the need for costly down time for weld repair or on-site machining
   of damaged hubs.
-------------------------------------------------------------------------------------------
•  Dur-O-Seal has a zero extrusion gap which allows for high
   pressure capacity, and ensures no loss of performance.
-------------------------------------------------------------------------------------------
•  Note: Dur-O-Seal is not intended for permanent installations
   where 'O' ring seals are not to be used due to operating
   conditions.
