3M FP-301-1 Pipe and Tube

3M FP-301-1/4-100'-CLEAR-SPOOL is a thin-wall heat-shrink tubing designed for reliable electrical insulation and mechanical protection in compact harnesses and exposed environments. As part of the FP-301 family, this 1/4-inch nominal, clear tubing balances electrical performance with physical and chemical properties, making it suitable for general industrial and military applications that require insulation, strain relief, or jacket protection of wires and splices. A key spec is its minimum shrink temperature of 100°C (212°F), ensuring dependable shrinkage without exposing components to excessive heat. Each 100-foot spool provides ample length for multiple repairs or harness projects, with the clear material allowing visibility of underlying conductors during installation and inspection.
