3M 7000133508 Heat Shrink Thin-wall Tubing FP301 1/2 in

Product Description

The 3M 7000133508 is a thin-wall heat shrink tubing from the FP-301 series, designed to provide reliable insulation and mechanical protection for electrical wiring and connections. At 1/2 inch diameter and 48 inches in length, this tubing delivers a consistent shrink ratio suitable for bundling, strain relief, and insulation of conductors in demanding industrial and military environments. Licensed electricians and maintenance technicians working on control wiring, panel builds, and field repairs rely on this product for dependable dielectric protection across a wide range of operating conditions.

FP-301 thin-wall heat shrink tubing is suited for both industrial and military-specification applications where electrical, physical, and chemical performance must meet rigorous standards. Typical use cases include wire harnessing, terminal insulation, cable marking, and connector protection in electrical panels, HVAC control wiring, and equipment manufacturing. Each piece is sold as an individual 48-inch length.

Key Features

• Thin-wall construction allows for compact installation in tight wire bundles
• Balanced electrical, physical, and chemical properties for industrial and military use
• 1/2 inch recovered diameter suitable for mid-range wire and connector sizes
• 48-inch length provides flexibility for cutting to required segment lengths
• Consistent shrink performance supports repeatable, professional-quality terminations

Compatibility

Designed as an OEM-style heat shrink solution for general electrical wiring, connector insulation, and cable protection in industrial and military applications.

Installation Notes

Installation is typically performed by licensed electricians or qualified technicians. De-energize all circuits before applying heat shrink tubing to any live wiring or terminations. Apply heat evenly using an appropriate heat gun, working from the center outward to prevent trapping air. Refer to NEC guidelines for proper insulation and conductor protection requirements in your jurisdiction.
