Lipstar™ lip sealing system

Lipstar™ is the new name for the proven sealing system with double lip seals for circular ducts from Aerotechnik E. Siegwart GmbH!

  • All of our fittings, shut-off valves and round volume flow regulators, as well as our optional throttle valves, are factory-fitted with our double-lip sealing system.
  • Lipstar™ seals are made from non-ageing EPDM. Very good resistance against low aggresive vapors and chemicals.
  • Lipstar™ fulfills the highest airtightness class D according to DIN EN 12237 through our special double lip sealing!

Order.-Nr. : 9xx

Order: 9+ Order number of the fitting with smooth end
Example: Bend 90° (Order-Nr. 24) ø 200 mm + double lip sealing → Order number: 924

Lipstar™ seals are made from non-ageing EPDM.

  • Very good resistance against low aggresive vapors and chemicals
  • Long-term temperature resistance from -30°C to +100°C (short-term from -50°C to +120°C)

With our Lipstar™ system the lip sealing sits tight on the fitting through seam and residual stress without aluminium tape and beading of the push fit ends

  • Low mounting effort: No gluing / No additional sealing
  • No leakage or accumulation of very small particles and dust respectively due to misalignment
  • Lipstar™ fulfills the highest hygienic standards according to VDI 6022
  • If required the lip sealing can easily be removed, e.g. for on-site coating or cladding of the mounting parts and be remounted afterwards
  • Beading and mounting of the lip sealing by the customer is possible – no double storage

Highest dimension accuracy of the fittings and circular control components by press calibration during the
shaping of the lip sealing seam.

Lipstar™ fulfills the highest airtightness class D according to
DIN EN 12237 through our special double lip sealing!

  • Minimal leakage and pressure drop in the system
  • Thus Lipstar™ is energy-saving and thereby eco-friendly
  • Reduction of the mounting effort
  • No or minimal noise emission
