Stabilized sealing performance PTFE Gasket

Since the spring is used for pressurizing in the live loading method, maintaining the packing tightening force for a long time will assure more stabilized sealing performance as compared with the conventional type seal unit.

For construction, the live seal unit comes in the following three types, depending on the application condition.

Reduced maintenance

It is possible to control the tightening force by zeroing the clearance between collar(spring cover) and packing retainer.

Since it is possible to check the decrease in tightening force by observing the clearance between collar and packing retainer, it becomes possible to know the time for re-tightening, and to execute the visible control.
