ePTFE gasket ring for steam vessels
KWO® MultiTex® DK Ring is a high-quality gasket material made from multidirectional expanded PTFE. The tape is especially designed for the sealing of steam boiler plugs and is suitable to seal man hole, head hole and hand hole covers of steam boilers.
The flexible material adapts excellently to sealing surfaces and compensates for any unevenness of the cover or flange surface. The ring ensures a very high tightness immediately after the installation and is particularly suitable for the pressure test with cold water. KWO® MultiTex® DK ring offers a lasting tightness under operating conditions and in applications with changing temperatures.
