Parker Hannifin’s TexLoc PTFE 4:1 heat-shrink tubing has one of the largest expansion ratio available in a PTFE tube, enabling it to protect objects that heat shrink with a smaller expansion ratio cannot shield. Operating in high temperatures (up to 500 degrees Fahrenheit), it was designed to protect instruments, cables and other objects from heat, abrasion and chemical hazards in harsh environments.
One of the biggest advantages to using TexLoc 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.
Parker TexLoc PTFE 4:1 heat-shrinkable tubing is available in an expanded state. When heated, the tubing conforms to the size and shape of the original object, providing a protective covering. It may also be used to repair electrical wiring, fittings, cords and other objects. For a full recovery, the expanded diameter should be 50 percent larger than the diameter of the object to be recovered over.
Parker TexLoc 4:1 heat shrink meets specification AMS-DTL 23053/12A Class 5, ASTM D2902 Type 1 and AMS 3584A. Sizes range from .078 inches expanded up to 1-1/4 inches. Custom sizes, long lengths, colors and samples are also available.
