The 3M 7010396217 is a thin-wall heat shrink tubing sold under the FP-301 product line, supplied on a 200-foot bulk spool in yellow. It is engineered to deliver a reliable balance of electrical insulation, physical protection, and chemical resistance across a wide range of demanding environments. The FP-301 series is a go-to choice for electricians, panel builders, and military-spec wiring technicians who need consistent, repeatable shrink performance on wire bundling, termination protection, and connector strain relief applications. The yellow color coding supports circuit identification in complex wiring assemblies.
This tubing is suited for industrial wiring harnesses, military and aerospace wire management, control panel builds, and general electrical insulation work. The 1/4-inch diameter size fits a common range of wire gauges and connector bodies. The 200-foot spool format supports high-volume production runs and field service kits where bulk stock reduces downtime. It is appropriate for both shop and field use wherever consistent heat shrink performance is required.
Designed as a general-purpose thin-wall heat shrink sleeving suitable for industrial, military, and commercial electrical wiring applications where FP-301 series tubing is specified.
Installation is performed by licensed electricians or qualified wiring technicians. De-energize all circuits and confirm zero-voltage conditions before applying heat shrink to any live wiring assembly. Use a calibrated heat gun set to the appropriate shrink temperature for the FP-301 material — avoid open flame sources, which can cause uneven shrink or tubing damage. Follow applicable NEC requirements and any project-specific military or industrial wiring specifications when selecting tubing size and color coding.
