Component Specifications

Definition
A precision sealing component designed for sample interface applications in industrial equipment, creating a hermetic seal between mating surfaces to prevent fluid/gas leakage, maintain pressure integrity, and prevent contamination of samples or process media. Engineered to withstand specific temperature, pressure, and chemical exposure conditions.
Working Principle
Creates a compression seal through elastic deformation when compressed between mating surfaces, filling microscopic imperfections to form a leak-proof barrier. The sealing force is generated by the material's elasticity and the compression load applied during assembly.
Materials
Nitrile rubber (NBR), Fluorocarbon (Viton/FKM), Ethylene Propylene Diene Monomer (EPDM), Silicone (VMQ), Perfluoroelastomer (FFKM), Polytetrafluoroethylene (PTFE). Material selection based on chemical compatibility, temperature range (-40°C to 250°C), and pressure requirements.
Technical Parameters
  • Hardness 70-90 Shore A
  • Compression Set <20%
  • Pressure Rating Up to 1000 psi
  • Tensile Strength 10-20 MPa
  • Temperature Range -40°C to 250°C
  • Elongation at Break 150-400%
Standards
ISO 3601, DIN 3771, AS 568A, SAE J515

Frequently Asked Questions

What is the difference between a sealing gasket and an O-ring?

Gaskets are typically flat seals used between static flanges, while O-rings are toroidal seals that fit into grooves and create seals through radial compression. O-rings provide better sealing for dynamic applications.

How do I select the right material for my sample interface?

Consider chemical compatibility with your process media, operating temperature range, pressure requirements, and regulatory compliance. Common materials include NBR for general purpose, FKM for chemical resistance, and EPDM for steam/water applications.

What causes O-ring failure in sample interfaces?

Common failure causes include chemical degradation, extrusion under high pressure, compression set (loss of elasticity), thermal degradation, improper installation, and incorrect sizing.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
