Product information

The Hecht Tri-Clamp Bellow is moulded from one piece, providing it’s own seal, meaning a separate gasket ring is no longer required. It is designed for optimal hygiene and to create optimal weighing results. These bellows have a conical asymmetrical design, the bottom angle of 60° prevents powder collection or blockage. No powders can remain behind, which is possible with the conventional spherical bellow. These bellows are suitable for contact with foodstuffs.

The bellow is available for Tri-Clamp connection and is pressure resistant up to 100 mbar. It is suitable for CIP.
