3M FP301-2 Black Polyolefin Thin Wall Heat Shrink Tubing

3M FP301-2 Black Polyolefin Thin Wall Heat Shrink Tubing

The 3M FP301-2 Thin Wall Heat Shrink Tubing is a black polyolefin heat shrink tubing engineered to insulate and protect wire and cable connections in electrical and industrial environments. This tubing family is available in expanded inside diameters ranging from 1/4 in. to 2 in., each supplied in a standard 48 in. length, letting installers match the tubing to the size of the cable, splice, or connector being covered. The polyolefin material construction combines flexibility with reliable coverage, shrinking down snugly around cables, splices, and connectors to deliver a low-profile finish without adding excess bulk. Its black color provides a clean, uniform appearance for cable runs and bundles that require a finished, professional look, making it a practical choice for OEM, MRO, and field service applications.
