Thin Wall Heat Shrinkable Tubing 4:1 8/2 black
Art.-No. 341-08020 | EPS-400-8/2-PO-X-BK

EPS300 and EPS400 offer high shrink ratios and protection against humidity.

Heat Shrink Tubing 4:1 with adhesive

EPS-400 is a flexible and thin wall heat shrink tubing with a co-extruded hot melt adhesive inner wall.
They have high shrink ratios which makes them ideally suited for shrinking onto components with highly varying diameters.
The adhesive flows well to provide an environmental sealing of complex parts and protect against moisture.
