General purpose flexible polyolefin tubing is ideal as a shrink-fit electrical insulation over cable splices and terminations and for lightweight wire harness covering, wire marking, wire bundling, component packaging, and fire resistant covering. It has a 2:1 shrink ratio. When freely recovered, the tubing will shrink to 50% of its original internal diameter. Kit contains 133 pieces of tubing in a variety of sizes (3/32", 1/8", 3/16", 1/4", 3/8", 1/2") and colors (black, red, white, yellow, blue, green, clear), packaged in a rugged translucent plastic box, (11" x 7" x 2-1/2").
