DK Ring - Steam Boiler Gasket

The DK Ring is a high-quality seal made of multi-directional expanded PTFE. The oval gasket is specially designed for sealing closures on steam boilers and is suitable for all sizes of internally sealing hand, head and manhole closures.

The flexible material conforms excellently to sealing surfaces and compensates for even large irregularities on the boiler lid and flange.

To prevent leaks during the start-up and shut-down process, we recommend the use of our special disc springs (which automatically readjust during load changes).
