Component Specifications

Definition
Sealing elements are precision-engineered components installed in nozzle rings to create hermetic barriers between moving or static parts, preventing the escape of liquids, gases, or contaminants. They ensure operational integrity by maintaining system pressure, protecting internal components from wear, and enhancing efficiency in applications like injection molding, spraying systems, and fluid transfer.
Working Principle
Sealing elements function by applying compressive force against mating surfaces, filling microscopic gaps to block fluid passage. In nozzle rings, they typically use elastomeric or polymeric materials that deform under pressure to conform to surface irregularities, creating a tight seal. Some designs incorporate spring-loaded mechanisms or lip seals that maintain contact during thermal expansion or vibration.
Materials
Common materials include Nitrile Rubber (NBR) for oil resistance, Fluorocarbon (FKM/Viton) for high temperatures, Ethylene Propylene Diene Monomer (EPDM) for steam/chemicals, Polytetrafluoroethylene (PTFE) for low friction, and Polyurethane (PU) for abrasion resistance. Hardness ranges from 70 to 90 Shore A.
Technical Parameters
  • Size Range 10 mm to 500 mm diameter
  • Pressure Range 0 to 100 bar

  • Operating Temperature -40°C to 250°C
  • Chemical Compatibility Resistant to oils, fuels, acids
Standards
ISO 3601, DIN 3770, ISO 6194
