Heat shrink Moulded Shapes
The use of our heat shrink moulded shapes in conjunction with our specialist heat shrink tubing makes it easy to fabricate complete jacketed wire and cable harnessing and interconnection systems of the highest quality.

Heat shrink moulded shapes are available for the complete range of electrical and electronic harnessing applications. They can be sealed with our special adhesives and encapsulants to ensure the proper degree of mechanical support, strain relief and environmental protection. 
Encapsulating the complete harnessing and interconnection system to the desired configuration is easily and neatly accomplished, with minimum weight and bulk.
