Clipperlon 600


Leader Clipperlon 600 Joint Sealant is made from 100% pure expanded PTFE. The universal gasket tape forms a thin, but yet strong, reliable gasket under compression, that is highly resistant to aggressive media and chemically inert. Even for the sealing of large, complex and damaged flanges - just peel of the covering paper from the adhesive backing and stick the Joint Sealant tape to the sealing surface - overlap the endings and close the jointing.


Product Data Sheet


Particularly for use with aggressive chemicals from pH 0 to 14 (except for molten alkali metals and elemental fluorine gas)Pressure up to 40 bar (higher pressures depending on the individual installation), to aggressive media and chemically inert, for the sealing of large, complex and damaged flanges


easy and quick installation, individual shaping and fast assembly, reduces scrap and sealing costs

Chemical Compatiblity

Patricularly suitable for use with hydrofluoric acid, but not pure hydrogen fluoride. Best for use with string alkalis, solvents, fuels, water, steam and chlorine. Other applications include solvents, fuels, water, oil, chlorine and caustics. A chemical resistance list is available upon request.

Delivery Options
