Kalrez® Tri-Clamp® gaskets

Kalrez® is a high quality sealing material for use in food, beverage and pharmaceutical applications.  Kalrez® Tri-Clamp® gaskets are designed for high temperature processes and have a great chemical resistance. They also avoid compression set issues and high static friction, which can cause intrusion in the process line.

Due to these properties, Kalrez® can provide a solution in complex applications and/or extreme conditions, for example in WFI or SIP/CIP processes. The gaskets are well-known for their high hardness, high temperature and chemical resistance, low static friction (low stiction), and extended lifetime. The LS390 seals are also easy to identify, because of their unique grey color.
