B2 - Colored Flexible, 2:1 Ratio - 4Ft. Length

  • Category: Heat Shrink Tubing
  • Brand: Sumitomo

For more varieties of colors and sizes please see B2 spooled

Colored Flexible Polyolefin, 4 foot length, 2 to 1 Ratio, for clear see product A2.

SUMITUBE B2 is a very flexible, flame-retarded, radiation-crosslinked heat shrinkable polyolefin tubing which meets all of the material and functional requirements of Military Specification AMS-DTL- 23053/5, Class 1 and Class 3. B2 is recommended for use in general purpose applications such as wire marking, color coding, and electrical insulation of light wire harness assemblies. For higher expansion ratio versions see B2(3X), B2(4X), and B2(4XC).
