A2 - Clear Flexible, 2:1 Ratio - 4Ft. Length

  • Category: Heat Shrink Tubing
  • Brand: Sumitomo

For sizes not listed under the 4ft., please see A2 SPL.

Clear Flexible Polyolefin, 4 foot length, 2 to 1 Ratio, for colors see product B2 4FT.

SUMITUBE A2 is a flexible, clear polyolefin heat-shrinkable tubing which meets all of the material and functional requirements of Military Specification AMS-DTL-23053/5C, Class 2. A2 is recommended for general purpose applications such as electrical insulation or light weight harness jacketing, where visual inspection of the substrate is desirable. For 3:1 shrink version see A2(3X).
