1 foot of 80mm Inside Diameter Polyolefin Black Heat Shrink Tubing with a 2:1 shrink Ratio. This tubing is opaque, and great for use when you need to make something light imperviable. I use this tubing to fit around 3" diameter (76mm) PMTs and scintillator crystals to make a light-tight shielding or housing.

Sold and shipped by the foot. When ordering more than 1 piece, please specify if you have a preference to ship as a continuous piece. I have other sizes of large diameter Black Polyolefin Heat Shrink Tubing available as well, please ask.
