3M FP301 Black Heat Shrink Tubing, 48-Inch

3M FP301 Flexible Polyolefin Heat Shrink Tubing, Black, 48-Inch with Header Label

The 3M FP301 Flexible Polyolefin Heat Shrink Tubing is a single wall (thin) heat-shrink product designed to insulate, protect, and organize wire splices, terminations, and cable ends. Supplied in a ready-to-use 48-Inch length with an attached header label, this black tubing allows electricians, contractors, and maintenance technicians to identify, sort, and manage sections before installation without measuring or cutting from bulk stock. Manufactured from flexible polyolefin, the tubing shrinks down snugly over connections to help provide a clean, protective covering for a range of wire and cable applications. The header label design keeps job-site inventory organized, making it easier to locate the correct length and color of tubing when working across multiple circuits, panels, or repair jobs.

Key Features
