Weicon DF 175 is a patented thread sealing tape made from 100% PTFE that provides a permanent and secure seal for nearly all metal and plastic threads. Weicon DF 175 reliably compensates for gaps in the threads and forms a PTFE film of the required thickness when screwed together. This film is extremely resistant to almost all chemicals, including the most aggressive solvents, alkalis, and acids. It is non-flammable and functions reliably within a temperature range of -200°C to +240°C. Very economical: one roll can replace up to 20 rolls of PTFE tape (12 mm x 0.1 mm x 12 m). Unlike other sealing materials, where the fabric merely serves as a carrier for the actual sealing agent, Weicon DF 175 is the sealing material itself. Thus, separation of the carrier and sealing material over the lifespan of the connection is impossible. It is indefinitely durable and remains soft and flexible at all times.
