These parts allow an easy fit and quick connection between two elements in the modular system, surrounding the two flanges to create a joint. They are attached using bolts. Total sealing is achieved with a rubber seal, which makes this section ideal for use in fine powder conduits or for systems where no air loss is permitted.

These are rubber seals which are used to ensure airtightness in perimeter conduit connections. They are essential in powder collection and pneumatic transport installations. They reduce air leakage so that head loss in conduits is therefore also reduced.

These parts are attached to the ends of any tube or accessory by turning them between the end flange and the bead at either end of MULTIFORM system tubes, or by welding, if the tube sections are KMH system units. The parts are locked together by means of bolts.
