The 3M 7100020133 is a thin-wall heat shrink tubing supplied on a 250-foot bulk spool, sized at 3/16 inch diameter and finished in green. Designated as FP-301 series, this tubing is engineered to deliver a reliable balance of electrical insulation, physical durability, and chemical resistance. It is used across industrial and military-grade wiring applications where consistent shrink performance and color-coded identification are required. Licensed electricians, military depot technicians, and industrial maintenance professionals typically work with this product when bundling, insulating, or protecting wire terminations and cable assemblies.
This tubing is suited for applications demanding dependable insulation in environments where exposure to chemicals, abrasion, or mechanical stress is a concern. The green color supports circuit or wire identification in multi-conductor installations. The 250-foot spool format makes it practical for shop use, service vans, or production environments where repeated cuts to length are needed rather than single-use pre-cut pieces.
Designed as an FP-301 series thin-wall heat shrink tubing for general industrial and military wiring, termination insulation, and cable bundling applications requiring 3/16 inch diameter coverage.
Installation is typically performed by licensed electricians or qualified wiring technicians. De-energize all circuits completely before applying heat shrink tubing to any termination or conductor. Use a calibrated heat gun rather than an open flame to apply uniform heat and avoid scorching the tubing or damaging adjacent insulation. Follow applicable NEC guidelines for insulation continuity and wire identification color standards in the specific installation environment.
