Our highlight for the perfect seal –
Ulith 240 (Twineflon®)

Revolutionary, patented thread sealing strips made of 100 % PTFE for sealing metal and plastic threads. Ulith 240 can change its shape, and so forms a PTFE film in the exact thickness required, when connecting the thread. Previous thread sealing products are static, and retain their original form.


Ulith 240 is extremely soft and flexible. The strand fills the existing gaps when screwing in the thread, and creates a guaranteed sealed connection!

Due to the exclusive use of pure PTFE in the production of Ulith 240, all the known advantages of this raw material could be used:

Our highlight for the perfect seal – Ulith 240 (Twineflon) - WBV worldwide


Wind Ulith 240 in the thread direction, starting at the beginning of the pipe, randomly, on approx. 10 mm of the thread. The strand should therefore overlap at some points.

Cut the strand with the 360° knife, and press the end of the strand into the thread. Press 2-3 drops of the lubricant provided, directly onto the Ulith 240 strand, and distribute over the wrapping. Screw on counterpart and tighten with pliers, adjust if necessary (backtwists up to 45° have been tested and certified).


Ulith 240 is delivered as a 175-m spool, in a specially developed, handy plastic box, and can be used directly from this packaging. The protected 360° knife and the liquid installation aid are integrated in the packaging (12 boxes / display carton).
