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.
