The HellermannTyton ShrinKit 321-A is Dual Wall Heat Shrink Tubing with a 3:1 shrink ratio. The attractive and reusable kit is ideal for assembling and identification. The inner wall melts when heated and is forced into gaps. When the tubing cools down the adhesive forms a seal, preventing any moisture seeping in, thus protecting the components.
The black tubes are mainly used for the protection of connectors and splices, the clear tubing is ideal for the protection of printed label markers. The ShrinKit 321-A covers a wide range of applications due to its ideal 3:1 shrink ratio.
The size of the compartments can be changed by simply moving the yellow space dividers. This kit contains a range of general purpose tubing lengths clearly sorted. Four different sizes are included in black and transparent.
