HECHT Tri-Clamp

No separate gasket needed
Conical design against piling
Reusable metal rings (AISI 316L / DIN 1.4404)
Designed for optimal weighing

The Hecht Tri-Clamp Bellow is molded from one piece, providing its own seal, meaning a separate gasket ring is no longer required. It is designed for applications with stringent hygiene requirements and to create optimal weighing results. These bellows have a conical asymmetrical design. The bottom angle of 60° prevents powder collection, piling 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. Materials The HECHT tri-clamp and the HECHT hose clamp can be produced in silicone as well as EPDM, as well as Black Antistatic food contact compliant EPDM.
