Parflex Heat Shrink Boots (HSB) are designed to prevent moisture from entering the ends of Parflex Temptrace™ bundles. The ends of Parflex Temptrace™ bundles must be properly sealed against contamination from moisture to prevent product damage. Parflex Heat Shrink Boots are an excellent way to seal bundle ends for worry-free bundle operation in various Instrumentation applications.

The boots can be used on 1/4”, 3/8”, or 1/2” tubes, or as a seal for the heating cable. Where “After Shrinking” I.D. is larger than the tube size in the bundle, a silicone grommet or Room Temperature Vulcanizing (RTV) end sealant should be used in conjunction with the boot to ensure a complete seal. See the grommet selection list below or RTV data listed in CAT. 4200-M-2 for more information.
