Diameters 450 to 630 mm available upon request. The wall thickness is equalised by thicker U-shaped seals for 1 mm and thinner for 2 mm. The seal is only slipped over one of the two lips. Provided that the U seal is resistant enough to the materials used, no leakages have been found with condensed liquids in the pipe.

Our U-shaped seals combine an ideal profile with the perfect choice of materials.

The benefits:

  • Tear-resistant, compliant with food regulations (FOOD GRADE) and resistant to many aggressive chemicals thanks to vulcanisation
  • Maximum tightness through an ideal profile
  • Resistant to a broad range of substances due to large selection of materials available
  • Metal-detectable and FOOD GRADE thanks to special materials (DETECTABLE DESIGN line)
