  • Quick Connect pull-ring Ø 80 to 300 mm, extremely quick mounting.
  • Pull-ring with screw fitting Ø 60 to 400 mm

Versions: electro galvanized. Alternative: stainless steel (1.4301).

Same profile of pull-rings for piping with a thickness of 1 mm and 2 mm. The wall thickness is equalized by thicker U-shaped seals for 1 mm pipes and thinner
ones for 2 mm pipes. The U-shaped seal is only slipped over one of the two lips.

Lip seals are available in NBR, silicone, conductive EPDM and Viton to meet the multiple chemical and thermal requirements.

Special tight connection:
The air leakage per connection measured at a differing pressure of 0,5 bar – e.g. 0,08 litres per hour on a diameter of 80 mm and 1,8 l/h on a diameter of 300 mm – are far below the admissible values of DIN EN 12237, class D. The requirements for nuclear plants (KTA 3601) of max. 10 litres per hour and square meter pipe surface are below the limits. Provided that the U-shaped seals are resistant enough, no leakages have been found out with condensed liquids in the pipe.

Connections of 1.5 mm and 2 mm thick piping with up to Ø 300 mm and 1 mm thickness for Ø 80 mm have been certified as shock-explosion proof up to 3 bar overpressure. Surge pressure proof pipelines with a diameter of more than 300 mm have to be installed with loose flange connections.

Bulk goods conveying and plants for air technique with differential pressures up to 50.000 Pa (500 mbar, 5.000 mm WC).
