The 3M 7010320050 is a thin-wall heat shrink tubing supplied on a 500-foot bulk spool. Part of the FP-301 series, it is designed to provide reliable insulation, strain relief, and protection for wire bundles, terminals, and electrical connections in industrial and military-grade environments. The tubing has a 3/32-inch recovered diameter and is produced in white. It is installed by electricians, field technicians, and MRO maintenance crews using a heat gun or oven to achieve a clean, conforming sleeve over conductors and components.
FP-301 thin-wall heat shrink tubing is suited for a broad range of applications including wire harnessing, cable marking, component insulation, and connector backshell protection. Its balance of electrical, physical, and chemical properties makes it appropriate for both commercial industrial assemblies and military specification work where consistent, repeatable performance is required. The 500-foot spool format is intended for production environments and service shops with high-volume tubing demand.
Designed as an OEM-style heat shrink sleeving solution for small-diameter wire, terminals, and electrical connections requiring thin-wall insulation protection in industrial or military assemblies.
Heat shrink tubing of this type is installed by electricians and electronics technicians following applicable NEC and workmanship standards. De-energize all circuits before sleeving terminals or conductors. Apply uniform heat with a calibrated heat gun, moving continuously to avoid scorching the tubing or damaging underlying insulation. Do not use an open flame as a heat source.
