About the M23053/5-104-4 Heat Shrink Tubing
M23053/5-104-4 is a thin-wall heat-shrinkable insulation sleeving supplied to MIL-DTL-23053/5, the military specification for flexible, cross-linked polyolefin tubing. This dash size is the 1/8 in supplied diameter with a 2:1 shrink ratio, and the -4 colour code denotes yellow. The item is designated fluid resistant with a 125 °C temperature rating, per the product description. Small-diameter M23053/5 sleeving of this kind is used to insulate individual wires, cover crimped terminations, and apply colour identification at the wire level within aerospace and industrial harnesses. The specification family provides high resistance to liquids and chemicals; being single wall and unlined, it insulates and identifies rather than environmentally sealing a joint, for which adhesive-lined dual-wall products are used instead. It recovers with standard hot-air tooling during harness assembly.
