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.

How do I select the size?

Use the unshrunk and recovered internal diameters in the table to check your application. The 12 mm figure is the nominal size designation. The dimension card shows the supplier reference values for this nominal size.
