Standard Put-up  
  O2B2 is a flexible heat shrinkable polyolefin tubing with a modified polyamide
  adhesive inner wall which melts and flows to seal components within.
   
  O2B2 is recommended for applications in environmental conditions which require
  sealing against moisture. (For clear use O2C)
