Other Benefits of O-Rings:

  • Form an essential part of any device
  • Cost-effective
  • Very reliable and strong
  • Resist harsh environmental and chemical reactions

In the medical industry, O-rings are used in respiratory equipment, drug delivery devices, fluid transfer devices, pumps, and so much more.


Also called oil seals or rotary shafts, lip seals are durable, flexible rings made of elastomer. Lip seals are wear-resistant, making them ideal for securing the barrier between moving and stationary components in a machine. By sealing gaps in machinery, lip seals prevent contaminants from entering the system and stop lubricants from leaking.
