定义
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.
工作原理
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.
材料
Nitrile rubber (NBR)Fluorocarbon (Viton/FKM)Ethylene Propylene Diene Monomer (EPDM)Silicone (VMQ)Perfluoroelastomer (FFKM)Polytetrafluoroethylene (PTFE). Material selection based on chemical compatibilitytemperature range (-40°C to 250°C)and pressure requirements.
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%
标准
ISO 3601DIN 3771AS 568ASAE J515

常见问题

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.
