Peroxide-Cured Silicone Rubber Tubing

NSF-51 Silicon Tubing
Properties
Component Supply offers silicone tubing in the dimensions indicated on the chart below. This silicone tubing does not contain sulfur or any other acid-producing chemicals, so the risk of staining, corroding, or deteriorating other materials is mostly eliminated. Even over an extended time, this tubing is highly resistant to UV, ozone, gases, and moisture. It is not recommended for implantable or continuous steam applications. However, it can be low pressure steam sterilized in-line or autoclaved at up to 250°F in a normal autoclaving cycle with limits. When exposed to repeated steam sterilization or long-term high temperature or pressure it will eventually relax, become gummy and need to be replaced.

Markets & Applications ▼
Silicone tubing is utilized in various markets including medical, dental, electronics, and food processing. Other end-uses are:
  • Appliances
  • Beverage service
  • Deionized water transfer
  • Computer
  • Food service
  • Gaskets, seals, &aamp; 'O'-rings
  • Hot water feeds
  • Insulation Sleeving
  • Laboratory tubing
  • Thermal Protection
Custom Fabrication & Contract Manufacturing ▼
Although we stock large volumes of this product for efficient and competitive distribution, we also seek to provide application-specific functionality to researchers and product designers by limiting minimum orders and cutting customer-specified lengths as short as a 1/4". For more custom fabrication information, please contact a Component Supply representative who can inform you of the best options for your specific application.
