Component Specifications

Definition
A toroidal-shaped elastomeric seal designed to create a static or dynamic barrier against fluid or gas leakage in mechanical systems, specifically used in drain valves to prevent unwanted discharge and maintain system integrity under varying pressure and temperature conditions.
Working Principle
Works by compression between mating surfaces, creating a sealing force that deforms the O-ring to fill microscopic gaps, preventing fluid passage through elastic recovery and surface contact pressure.
Materials
Nitrile rubber (NBR), Fluorocarbon (FKM/Viton), Ethylene Propylene Diene Monomer (EPDM), Silicone (VMQ), Polyurethane (PU) - selected based on chemical compatibility, temperature range (-40°C to 200°C), and pressure requirements.
Technical Parameters
  • Hardness 70-90 Shore A
  • Inner Diameter 5-500 mm
  • Pressure Rating Up to 40 MPa static, 15 MPa dynamic
  • Temperature Range -40°C to 200°C
  • Cross-Section Diameter 1.5-10 mm
Standards
ISO 3601, AS 568A, JIS B 2401, DIN 3771
