Component Specifications

Definition
A toroidal elastomeric sealing component designed to create a static or dynamic seal between the ceramic membrane filter element and its housing in industrial filtration systems. It prevents fluid bypass, maintains pressure differentials, and ensures contamination-free operation by sealing the interface between the porous ceramic element and the filter assembly.
Working Principle
The O-ring creates a seal through elastic deformation when compressed between two mating surfaces (filter housing and ceramic element). Under system pressure, it deforms to fill microscopic imperfections, creating a barrier that prevents fluid leakage while allowing for thermal expansion and mechanical movement of the ceramic membrane.
Materials
Fluoroelastomer (FKM/Viton) or Ethylene Propylene Diene Monomer (EPDM) for chemical resistance; Nitrile Rubber (NBR) for oil-based applications; Perfluoroelastomer (FFKM) for extreme chemical environments. Hardness: 70-90 Shore A. Temperature range: -40°C to 200°C depending on material.
Technical Parameters
  • Inner Diameter 10mm to 200mm
  • Compression Set <20% after 24h at 150°C
  • Pressure Rating Up to 10 MPa (static), 3 MPa (dynamic)
  • Temperature Range -40°C to 200°C
  • Chemical Compatibility Resistant to acids, alkalis, solvents per material selection
  • Cross-Section Diameter 1.5mm to 5mm
Standards
ISO 3601-1, DIN 3771, AS 568A, JIS B 2401

Frequently Asked Questions

What material is best for O-rings in ceramic membrane filters?

FKM/Viton is recommended for most chemical filtration applications due to excellent chemical resistance. EPDM is suitable for steam or hot water applications, while FFKM is used for aggressive chemical environments.

How often should O-ring seals be replaced in ceramic filters?

Typically every 6-12 months or during routine maintenance, depending on operating conditions. Signs of replacement include visible cracks, flattening, or increased leakage.

Can O-rings handle thermal cycling in ceramic filters?

Yes, properly selected elastomers (especially FKM and EPDM) accommodate thermal expansion of ceramic elements from -40°C to 200°C while maintaining seal integrity.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
