National Standard 21206 Heavy Wall Heat Shrink Adhesive Lined Black 6" (8 Ga)

The Heavy Wall Heat-shrink is for direct burial of heavy duty electrical cable, where environmental protection is necessary. This Heavy Wall Heat shrink tubing is supplied with an adhesive layer, adding a water tight seal to the strain relief the tubing provides. When exposed to heat a tad lower then the activation temperature of the Heavy Wall Heat shrink, the inner layer (adhesive) begins to melt and flow as a standard "glue-stick". When the heat shrink tubing shrinks and cools down, the inner layer forms an adhesion layer between the tubing and the connector or wire. This provides the watertight seal and protects the connector/wire in direct burial and submersed applications. Useful for marine grade applications as well as Heavy Duty.
