3M 7010399009 Heat Shrink Tubing FP301 1/2 in Clear 6 in 10 Pk

Product Description

The 3M 7010399009 is a thin-wall heat shrink tubing from the FP-301 series, designed to provide reliable insulation, strain relief, and environmental protection on electrical connections, wire splices, and conductor terminations. The FP-301 formulation delivers a well-balanced combination of electrical, physical, and chemical resistance properties, making it suitable for demanding industrial and military-grade wiring applications. Each piece measures 6 inches in length with a nominal recovered size of 1/2 inch diameter and features a clear finish for easy visual inspection of the connection underneath. Licensed electricians and experienced wiring technicians are the primary installers.

This tubing is used across a broad range of applications including panel wiring, harness fabrication, military and aerospace wire assemblies, and general industrial electrical work. The clear color makes it practical in environments where labeling or visual confirmation of conductor identity is required after shrinking. Each pack contains 3 pieces at 6 inches each, and the minimum order quantity is 10 packs, making this a suitable option for shop stock or production-line use.

Key Features

• Thin-wall FP-301 construction provides electrical insulation and abrasion resistance
• Clear finish allows visual inspection of the underlying conductor or connection
• 6 inch piece length suits standard splice and termination work
• 1/2 inch nominal diameter fits common wire gauge ranges for mid-size conductors
• Rated for industrial and military wiring applications
• Sold in packs of 3 pieces; minimum order quantity of 10 packs

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeve suitable for industrial and military electrical wiring applications requiring insulation and strain relief on splices and terminations.

Installation Notes

Installation is performed by licensed electricians or qualified wiring technicians in accordance with NEC guidelines. De-energize all circuits before applying heat shrink tubing to any connection. Use a calibrated heat gun rather than an open flame to apply uniform heat and achieve consistent shrink without damaging the tubing or underlying insulation. Ensure the conductor and connection are clean and dry before sliding the tubing into position.
