Low Temperature O-Ring Solutions

Finding the right low-temperature o-ring solution can be critical to both the success and safety of a design — and FEP encapsulated o-rings are an excellent solution.

Low Temperature and Cryogenic Applications

Cryogenic refers to temperatures below freezing and extending to absolute zero (-460°F / -273°C), while low-temperature environments are typically defined as below -25°F. Common chemicals that are stored or transported at cryogenic temperature include 

  • Liquid Oxygen (LOX), -297°F
  • Liquid Natural Gas (LNG), −265°F
  • Liquid Hydrogen (LH2), -423°F
  • Liquid Nitrogen (LN2), –130°F 
  • Liquid Helium, -452°F 

The industries that involve low temperatures include aerospace, energy, electronics, chemical processing, food, pharmaceutical, and medicine. Quantum computing, rockets, and MRI machines are just a few specific examples where cryogenic o-rings are needed.

Canted Coil Springs: Benefits for Medical Applications

What is a Canted Coil Spring?

Canted coil springs (also known as cant or slant coil springs) are not your typical spring, and this becomes obvious when you take a look at the three different types of tasks they support:

  • Acting as a mechanical connector
  • Energizing seals for better performance
  • Providing EMI/RFI shielding
  • Serving as a multiple contact point conductor
