Ordinarily, you don't want something to shrink in the heat (say, for example, your favorite T-shirt). However, there are times when that's exactly what you want. Sumitomo Electric Interconnect Products, Inc. specializes in heat-shrinkable products, serving customers in a variety of industries such as electronics, medical, communications and aerospace. We have their solder sleeves, which are high-temperature solder termination devices. We also carry the Sumitube STS sealed crimp splice kits. These are environmentally sealed, compact wire splices. There are Sumitomo solder sleeves in nickel or tin, and certain models are braided. You'll find termination sleeves are for silver, nickel or tin plated shield termination in various sizes. Their Sumimark tubing is made from shrinkable polyolefin and is for general purpose use.
