Screw Seals

Specially designed screw seals help to ensure the desired sealing effect in flange and screw applications.

The static gaskets which are made from an elastomer material, and depending on application supplemented with a lip, are fitted with a stainless-steel ring.

Tightening the screw will now press the elastomer part against the screw and achieve the desired sealing effect.
