The HellermannTyton 323-50630 is an adhesive-lined heat shrinkable tubing constructed for a 4:1 medium wall and a 1m length. It is constructed from 63/19 qualified polyolefin and has a black finish. This heat shrinkable tubing is ideal for use over a variety of connections such as cable, connector, and component ends. It offers strong protection to the connections against moisture, vibration, and corrosion. The self-adhesive lining provides a superior seal by creating a liquid tight seal, and once a heat source is applied, the tubing forms a tight, secure grip around objects like cables and terminals. The medium wall heat shrinkable tubing provides balance between flexibility and strength, and will enable a solid, reliable connection that is built to last.
