The 3M 7100030001 is a thin-wall heat shrink tubing supplied on a 100 ft spool in black, designated under the FP-301 product series. FP-301 tubing is engineered to deliver a balanced combination of electrical insulation, physical protection, and chemical resistance, making it well-suited for wire bundling, termination protection, and component insulation tasks across industrial and military-grade applications. At 3/16 inch nominal diameter, this tubing fits a range of wire gauges and connector bodies commonly encountered in low-voltage wiring, panel work, and field repair scenarios. Licensed electricians and experienced technicians are the typical installers.
FP-301 thin-wall heat shrink tubing is used across a broad range of industrial, electrical, and mil-spec applications including wire harnessing, terminal insulation, strain relief, and corrosion protection on conductor ends. The 3/16 inch size is a common fit for smaller gauge wires and pin-style connectors. The black color provides UV exposure resistance and is a standard choice for general-purpose electrical and instrumentation work. Each spool contains 100 ft of tubing, with a case quantity of 300 ft total.
Designed as an OEM-style replacement and general-use heat shrink tubing for industrial, commercial, and mil-spec electrical wiring applications requiring thin-wall sleeving at the 3/16 inch nominal diameter.
Heat shrink tubing should be installed by a qualified electrician or trained technician following applicable NEC requirements for the circuit type and environment. Confirm the tubing inside diameter is appropriate for the conductor or termination before applying heat. Use a heat gun calibrated to the tubing manufacturers recommended shrink temperature and apply heat evenly along the length of the tubing to avoid uneven shrinkage or damage. De-energize all circuits before applying the tubing to live conductors.
