Frequently Asked Questions (FAQ) about Rubber Bellows

O-rings are essential sealing components used across a variety of industries, including automotive, aerospace, plumbing, hydraulics, pneumatics, and medical devices. They provide a leak-proof seal in applications such as engines, pumps, valves, fuel systems, and industrial machinery, preventing fluid or gas leakage under various pressure and temperature conditions.

O-rings are made from a variety of elastomers to suit different environments:
 
  • Nitrile (NBR): Ideal for automotive and industrial use, resistant to oils and fuels.
  • Viton® (FKM): Offers high-temperature and chemical resistance for harsh industrial conditions.
  • EPDM: Excellent for water, steam, and weathering resistance.
  • Silicone: Offers high flexibility and temperature resistance, widely used in medical and food applications.
  • Neoprene: Known for weather, oil, and ozone resistance, suitable for general-purpose sealing.
When selecting an O-ring, keep these factors in mind:
 
  • Material compatibility with the fluid, chemicals, and temperature involved.
  • Size and hardness (durometer) for a proper seal and optimal compression.
  • Pressure requirements for both static and dynamic sealing applications.
  • Operating temperature range for high-heat or cold environments.
Ensure the O-ring meets industry standards and certifications, like FDA-approved O-rings for food applications.
O-ring failure can be caused by several factors:
 
  • Incorrect material selection that doesn’t match the chemicals or temperature.
  • Over-compression or improper installation, leading to cracks or deformation.
  • Abrasion or excessive wear from friction in dynamic applications.
  • Swelling or hardening due to exposure to incompatible fluids.
  • Thermal degradation from exposure to extreme temperatures.

To maximize the lifespan of O-rings:

  • Choose the correct material tailored to the specific application.
  • Lubricate O-rings properly to reduce friction and wear.
  • Ensure proper installation to avoid over-compression or stretching.
  • Store O-rings in a cool, dry place, away from direct sunlight and ozone exposure.
  • Regularly inspect O-rings and replace any worn or damaged ones before failure.
