O Rings - What They Do

O Rings are circular elastomer seals used to prevent the escape of fluid or gas between two mating surfaces. They can be used in static (no movement) or dynamic (moving parts) applications, forming a tight barrier that resists pressure, vibration, and temperature changes.

• Hydraulic cylinders
• Pumps and valves
• Compressors
• Automotive engines
• Machinery maintenance
• Oilfield and construction equipment

Sub-Categories of O Rings

A) By Application Type:

• Static O Rings:
  Used for sealing between non-moving parts; ideal for flange joints, valve bodies, and fittings.
• Dynamic O Rings:
  Designed for movement applications such as reciprocating, rotating, or oscillating shafts.
• Vacuum O Rings:
  For vacuum sealing applications in laboratory or gas systems.
• High-Pressure O Rings:
  Reinforced compounds and back-up rings used in heavy-duty hydraulics.
• Food & Pharma Grade O Rings:
  Silicone or EPDM-based; compliant with FDA and hygienic requirements.
• Chemical-Resistant O Rings:
  Made from Viton®/FKM/PTFE for strong acids, solvents, and fuels.
• Temperature-Resistant O Rings:
  For cryogenic or high-temperature use (from -60°C to +250°C).
• Conductive / Anti-Static O Rings:
  For electronics and explosive environments.
