When the heat is on, Parker manufactures PTFE high temperature heat shrink tubing, a fluoropolymer heat shrink tubing that protects components from heat, sparks and contaminants while handling long term exposure to  temperatures as high as 500°F (260°C).  When heated, the heat shrink conforms to the size and shape of the original object, providing a protective covering. The biggest advantage to using Parkers' PTFE 4:1 is its' ability to easily slip over objects with protrusions or irregular shapes and still provide a snug fit.   In addition, the thin wall promotes quick installations while keeping the tubing flexible. For a full recovery, the expanded diameter should be 50% larger than the diameter of the object to be recovered over.
