Parker 4:1Parker TexLoc says that its PTFE 4:1 heat-shrink tubing has the largest expansion ratio available in a PTFE tube, enabling it to protect objects that heat shrink with a smaller expansion ratio cannot. The tubing further features: 

  • The power to protect instruments, cables and other objects from heat, abrasion and chemical hazards in harsh environments. 
  • The ability to easily slip over objects with protrusions or irregular shapes, yet still provide a snug fit.  
  • The capability to conform to the size and shape of the original object, providing a protective covering when heated. 
  • A thin wall that promotes quick installations, while keeping the tubing flexible.
  • Operation in temperatures up to 500°F (260°C).
  • The flexibility to be used to repair electrical wiring, fittings, cords and other objects. 
  • Compliance with AMS-DTL 23053/12, Class 2.
  • Availability in 4-foot lengths, with sizes ranging from 0.078 inches (2 mm) expanded up to 1-1/4 inches (31 mm). 
  • The option of ordering custom sizes, long lengths, colors and samples.
