The 3M 7100026347 is a thin-wall heat shrink tubing sold under the FP-301 product line, supplied on a 100-foot bulk spool. It is designed to provide reliable electrical insulation, physical protection, and chemical resistance across a wide range of industrial and military wiring applications. The tubing installs by sliding over conductors, terminals, or splices and applying controlled heat to achieve a snug, uniform shrink. Electricians and maintenance technicians working in industrial facilities, panel shops, and military MRO environments are the primary installers of this product.
FP-301 thin-wall heat shrink tubing is suited for bundling and insulating wire harnesses, protecting solder joints and crimp terminals, and providing strain relief on cable assemblies. The clear finish allows visual inspection of connections after shrinking without removing the tubing. Its thin-wall construction makes it a practical choice where space is limited or where a low-profile sleeve is required. The bulk 100-foot spool format supports high-volume production and service shop use.
Designed as a general-purpose thin-wall heat shrink sleeve compatible with standard wire, cable, terminals, and solder splices requiring electrical insulation and environmental protection in industrial and military wiring assemblies.
Installation is performed by electricians or wire harness technicians using a heat gun or oven set to the appropriate shrink temperature for FP-301 material. De-energize all circuits and verify lockout/tagout procedures are complete before working on any live panel or harness. Slide the tubing over the connection before terminating where possible, and apply heat evenly along the length of the tubing to achieve uniform shrinkage without scorching.
