Note that with continued Raychem SCL shortages, some product may be substituted with Sumitomo manufactured tubing to the same military specification (AMS-DTL-23053/4 Class 1).  This is highlighted under the size options above

SCL is encapsulant-lined, heat shrinkable tubing that provides moisture resistance, strain relief, and electrical insulation for electrical splices, terminations, breakouts, and mechanical connections. SCL is constructed as a dual-wall tubing. The outer wall is a semirigid, crosslinked polyolefin, while the inner wall is a meltable polyolefin that flows with the application of heat. Heating SCL shrinks the outer jacket and melts the inner “encapsulant” wall to flow and fill surface irregularities.

While still hot, the tubing can be pinched and blocked to form a wire breakout. SCL provides a splash-resistant, moisture-resistant covering suitable for many applications.
