Peroxide-Cured Silicone Rubber Tubing

NSF-51 Silicon Tubing
Material Properties
This silicone tubing is 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 and ozone. 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 an excellent choice for applications involving temperature extremes. This tubing's strong electrical properties and self-extinguishing capability makes it a good choice for appliances and computer applications. While Component Supply provides some information for possible applications for this tubing, there are too many possible functions for a comprehensive description of uses in various industries. Therefore, when considering a potential application in your particular industry, please consider contacting one of our knowledgeable representatives who assist researchers and product designers in choosing the best products for their specific applications.

Custom Fabrication & Contract Manufacturing ▼
Component Supply offers silicone rubber tubing in the dimensions indicated on the chart below. 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 inch. Contact us for 1,000-foot pricing and custom fabrication information.

Quality, Compliance, & Regulatory▼
Silicone tubing meets the following:
  • Certified by the National Sanitation Foundation (NSF-51) for food equipment materials
  • Made from FDA-sanctioned ingredients
