KWO® MultiTex® DK Ring is a high quality gasket material made from biaxially expanded PTFE. The ring is especially designed for the sealing of steam boiler plugs.
KWO® MultiTex® DK gasket ring has been tested and homologised with the "d" rating for temperatures up to 250°C and 40 bar in accordance with the requirements of VdTÜV “Dichtung 100” instructions (formerly TRD401). This gasket ring 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.
