Component Specifications

Definition
A precision-engineered elastomeric sealing component designed specifically for vacuum nozzle systems, creating an airtight seal between mating surfaces to maintain consistent vacuum pressure, prevent contamination ingress, and ensure reliable material handling in automated systems.
Working Principle
Utilizes elastic deformation under compression to fill microscopic surface irregularities, creating a hermetic seal through controlled interference fit and material memory properties that maintain sealing force across temperature and pressure variations.
Materials
Typically FKM (Viton), EPDM, or silicone compounds with hardness 70-90 Shore A, temperature range -40°C to 200°C, vacuum-rated formulations with low outgassing properties (<1% TML, <0.1% CVCM per ASTM E595).
Technical Parameters
  • Vacuum rating 10^-3 to 10^-6 mbar
  • Inner diameter 10-50 mm
  • Surface finish Ra 0.4-0.8 μm
  • Compression set <15% (ASTM D395)
  • Pressure rating Full vacuum to 10 bar
  • Temperature range -40°C to 200°C
  • Cross-section diameter 1.5-5.0 mm
Standards
ISO 3601-1, DIN 3771, AS 568A, JIS B 2401

Frequently Asked Questions

What materials are best for vacuum nozzle O-rings?

FKM (Viton) offers excellent chemical resistance and high-temperature performance, EPDM provides good elasticity at lower temperatures, while silicone offers wide temperature range with minimal outgassing for high-vacuum applications.

How often should vacuum nozzle seals be replaced?

Typically every 6-12 months depending on cycle frequency, but monitor for compression set >20%, surface cracking, or vacuum pressure degradation exceeding 10% of specification.

Can standard O-rings be used in vacuum applications?

No, vacuum-rated seals require special formulations with low outgassing properties and specific compression set characteristics to maintain seal integrity under vacuum conditions.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
