Product description

Threaded sealing strip DF 175

Suitable for metal and plastic threads

WEICON DF175 is a patented 100% PTFE thread sealant that seals almost all metal and plastic threads permanently and safely. WEICON DF175 can fill the intermediate space between the threads and form a PTFE film of appropriate thickness during the screw fixing process . This film is resistant to almost all chemicals, even the most reactive solvents, corrosive solvents and acid solutions.


WEICON DF175 is non-flammable and can be used at temperatures ranging from -200 (-328 ° C) to 240 ° C (464 ° C). Compared with other sealants based on sealants, WEICON DF175 is itself a sealant. Therefore, separation of the base material and the sealing material does not occur during the service life of the threaded interface.
