DR-25-TW Technical Data
     
   
     
  Heat-Shrinkable, Flexible, Thin Wall, Chemical Resistant Tubing  
 
Applications: DR-25-TW is a flexible, fluid resistant elastomeric tubing. Developed from DR-25, this thin wall version is ideal for use where space and weight saving are important. It also offers excellent resistance to fluids at high temperature and to long-term heat exposure. It is fast to install and may be
used with other products from the Raychem System 25 range for compact and tough harnessing systems. The product is printed with the product description and size.
 
     
 
Installation: Minimum full recovery temperature: +175°C [347°F]. Shrink ratio 2:1.
