Platinum-Cured Silicone Medical Tubing

NSF-51 Silicon Tubing
Material Properties
Component Supply offers platinum-cured silicone rubber tubing in the dimensions indicated on the chart below. This silicone elastomer is platinum-cured for the highest degree of purity. It is reusable and able to withstand repeated sterilization. Its physical properties resist sticking and encrustation and will not support bacteria growth. The tubing is soft, pliable and contains no plasticizers, which could leach out and cause flow contamination or tube hardening. It is not recommended for implantable or continuous steam applications. 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 ▼
Markets utilizing this silicone tubing include pharmaceutical, biomedical, health and beauty, food and beverage handling. Specific end uses are:
  • Blood & fluid handling
  • Dialysis
  • I.V. Administration
  • Laboratory Uses
  • Surgical Drains
  • Peristaltic Pumps
  • Pharmaceutical Processing
Please contact us directly if you have any questions about your specific application.

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 offering custom fabrication of our products. Capabilities for custom cutting this tubing to customer requirements include lengths as short as 1/4"e;. When purchased in 50-foot lengths, this tubing comes sealed but should still be sterilized before use. For more custom fabrication information, please contact a Component Supply representative who can inform you of the best fabrication options for your use.
