KWO® MultiTex® DK Ring
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.
- excellent tightness from the installation on
- seals very well flange surfaces; avoids corrosion of the sealing surfaces
- flexible material adapts excellently to cover or flange surface
- resistant to stress due to changing temperatures
- full material resistance
- very good adaptability to rough sealing faces
- non-ageing, unlimited storable
- nontoxic, biologically inert
- non-flammable
- steam vessels
- silo systems
- food processing and pharmaceutical systems
- certificated and monitored by TÜV
- “VdTÜV Merkblatt Dichtung 100” (formerly known as TRD 401), correspond to test category “D“ up to 250°C/40 bar
- testes for an increased gab between lid and flange
- FDA 21 CFR 177.1550 tested
