For metal and plastic threads. WEICON DF 175 is a patented thread sealing cord made of 100% PTFE and seals almost all metal and plastic threads permanently and securely. WEICON DF 175 reliably compensates for the space between threads and creates a PTFE film with the required thickness when screwing. This film is extremely resistant to almost all chemicals, even the most aggressive solvents, alkalis and acids.
WEICON DF 175 is non-flammable and operates reliably in a temperature range from -200°C to +240°C (-328 to +464°F). In contrast to other sealing materials where the fabric only acts as a base for the actual sealant, WEICON DF 175 itself is the sealing material. The base material and the sealing material are therefore not separated over the service life of the screw connection.
WEICON DF 175 has an unlimited shelf life and remains permanently soft and flexible. WEICON DF 175 is very economical: One roll replaces up to 20 rolls of PTFE tape (12 mm x 0.1 mm x 12 m).

WEICON DF 175 is used
• For sealing almost all plastic and metal threads
• For pipes used to transport extremely aggressive media
• In conjunction with gaseous or liquid media, such as oxygen, propane, butane and many more
• In the drinking water sector
• In extreme temperature ranges between -200°C and +240°C (-328 to +464°F)
• In the solar sector
• Wherever a connection must be turned back (tested up to 45°) without weakening the sealing effect
