About the M23053/5-206-C Heat Shrink Tubing
MIL-DTL-23053/5 covers flexible, crosslinked polyolefin heat-shrinkable insulation sleeving; the part number is built as class digit, size identifier and colour code. In M23053/5-206-C the leading 2 is Class 2, which MIL-DTL-23053/5C furnishes in clear only and classifies as flammable — unlike Class 1 (flame resistant) and Class 3 (highly flame resistant) — so it should not be substituted where a flame-resistant sleeve is called for. Size identifier 06 is the 1/4 in size, with a minimum as-supplied inside diameter of .250 in (6.35 mm) recovering to a maximum .125 in (3.18 mm) and a recovered wall of .025 ± .003 in. The colour designator C denotes clear. Class 2 shares the −55 °C to +135 °C continuous operating range with Class 1, and the specification adds a clarity stability requirement that applies specifically to the clear material.

Typical applications
The reason to specify the clear Class 2 material is visibility: the joint underneath stays readable after recovery, so printed wire markers, splice barrels, colour-coded conductors and solder joints can all be inspected without cutting the sleeve back. At a recovered .125 in bore the 1/4 in size is a natural fit over in-line splices and small terminations on single conductors and light bundles. Because this class is flammable, it is normally used on bench and test assemblies and in open equipment rather than in flame-critical harness runs.
