Low Temperature Elastomers for Cold and Cryogenic Applications
In low temperature environments, standard elastomers become brittle, lose elasticity, and fail to maintain a reliable seal. That’s why specialized low temperature elastomers are essential for applications that demand flexibility and sealing performance in extreme cold—down to -30°C and beyond. From O-rings and custom molded parts to flexible tubing, these materials are formulated to retain their properties in sub-zero conditions and cryogenic systems.
Canyon Components offers a range of cold-resistant elastomers, including advanced blends of Silicone, FKM, FFKM, Teflon Encapsulated Steel Spring O-rings, and PTFE Spring Energized Seals, ideal for temperatures as low as -268°C.
Check with one of Canyon’s helpful product engineers for an expert material and manufacturing recommendation.
Features of Low Temperature Elastomers
- Cold Flexibility: Designed to remain pliable and elastic in environments below -30°C, ensuring leak-free performance during startup and steady-state operation.
- Cryogenic Capabilities: Select materials like PTFE Spring Energized Seals and Teflon Encapsulated Steel Spring O-rings perform at temperatures as low as -268°C, suitable for liquid nitrogen and other cryogenic media.
- Resilient Sealing: Maintain compression set resistance and sealing force even after temperature cycling and prolonged exposure to cold.
- Material Versatility: Available in standard and custom O-rings, molded parts, and extruded tubing to suit both static and dynamic sealing needs.
- Chemical Compatibility: Many cold-resistant elastomers also offer excellent resistance to fuels, oils, and cryogenic fluids.
Common Applications
- Aerospace & Aviation: Cold-weather aircraft systems, high-altitude seals, and rocket fuel lines require reliable performance at extreme altitudes and temperatures.
- Cryogenics & LNG: Sealing systems for liquid nitrogen, liquid oxygen, and liquefied natural gas (LNG) equipment operating at temperatures below -150°C.
- Automotive & EV Systems: Battery enclosures, coolant seals, and HVAC systems in electric and hybrid vehicles exposed to sub-zero climates.
- Scientific Research: Laboratory equipment and instruments that must maintain vacuum integrity or fluid handling in ultra-cold test chambers.
- Oil & Gas: Seals for arctic exploration tools, pipeline systems, and offshore drilling equipment exposed to freezing environments.

Pros of Low Temperature Elastomers
- Maintain flexibility and elasticity at temperatures far below freezing
- Resist cracking, shrinkage, and compression set under cold conditions
- Available in multiple forms: O-rings, tubing, and custom molded parts
- Options available for both chemical exposure and dynamic sealing
- Long service life in cryogenic and low-temp cycling environments
Cons of Low Temperature Elastomers
- Limited rebound at room temperature for some materials (e.g., PTFE-based options)
- Higher material and production cost for ultra-low temperature grades
- Custom formulations may require extended lead times or special tooling
- Not all low-temp elastomers offer simultaneous high-temp or high-pressure performance
