常见问题

What materials are suitable for food-grade sealing bodies?

FDA-approved silicone rubber (VMQ), EPDM, or fluorosilicone materials that resist food products, cleaning chemicals, and high temperatures while maintaining elasticity.

How often should sanitary gasket sealing bodies be replaced?

Typically every 12-24 months depending on usage frequency, cleaning cycles, and visual inspection for cracks, swelling, or permanent deformation.

Can food-grade sealing bodies withstand steam cleaning?

Yes, properly specified materials can withstand regular CIP/SIP processes with temperatures up to 140°C and chemical cleaning agents.
