Supplier reference specifications

Dimensions are supplier reference values. Nominal size and actual unshrunk internal diameter differ. Flat presentation describes the unshrunk profile. Use the internal diameter values to check fit. Recovered values come from the supplier dimension card.

Selection and installation

Check that the unshrunk internal diameter clears the largest part to be covered and that the recovered dimensions suit your cable or joint. Slide the tubing into place before completing a connection where necessary. Apply heat evenly using suitable equipment and check the finished fit after recovery. Select materials and heating conditions appropriate to your cable and surrounding components.
