Component Specifications

Definition
A precision-engineered sealing body designed specifically for food-grade sanitary gaskets, providing hermetic sealing between flanged connections in food processing machinery. It prevents leakage of fluids and contaminants while maintaining sanitary conditions required for food safety standards.
Working Principle
Creates compression seal between mating surfaces through controlled deformation when compressed between flanges, forming a barrier against fluid passage and microbial ingress while accommodating thermal expansion and mechanical stresses.
Materials
FDA-compliant silicone rubber (VMQ), EPDM, or fluorosilicone with food-grade certifications; Shore A hardness 50-70; temperature range -60°C to +230°C; resistant to oils, acids, and cleaning agents.
Technical Parameters
  • Thickness 1.5-6 mm
  • Diameter Range 10-500 mm
  • Surface Finish Ra ≤ 0.8 μm
  • Compression Set ≤ 20% (22h at 175°C)
  • Pressure Rating Up to 16 bar
  • Temperature Range -60°C to +230°C
Standards
ISO 9001, ISO 22000, FDA 21 CFR 177.2600, EC 1935/2004, 3-A Sanitary Standards

Frequently Asked Questions

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.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
