3M 7100025159 FP-301 Heat Shrink Tubing 1/2 in Blue 200 Ft

Product Description

The 3M 7100025159 is a thin-wall heat shrink tubing sold on a 200-foot bulk spool, designed for insulating, protecting, and bundling wires and connections across industrial and military-grade applications. Based on the FP-301 series, this tubing is engineered to deliver a reliable balance of electrical insulation, physical durability, and chemical resistance. The 1/2-inch diameter size accommodates a range of conductor and connector sizes common in electrical and wiring work. It ships on a continuous spool, making it practical for high-volume production or field use where multiple cuts are needed.

This tubing is suited for industrial wiring harnesses, military and aerospace wiring assemblies, panel wiring, and general electrical insulation tasks. The blue color aids in cable identification and organization within multi-conductor systems. Electricians, MRO technicians, and production line assemblers regularly use FP-301 series tubing when a cost-effective, thin-wall shrink solution is required without the bulk of adhesive-lined alternatives.

Key Features

• Thin-wall construction provides a low-profile insulation layer after shrinking
• Blue color supports wire and circuit identification in complex assemblies
• 200-foot bulk spool reduces waste and supports high-volume applications
• Balanced electrical, physical, and chemical resistance properties for demanding environments
• Suitable for both industrial and military wiring applications

Compatibility

Designed as an OEM-style thin-wall heat shrink solution for general electrical insulation and wire bundling applications requiring a 1/2-inch diameter shrink tubing.

Installation Notes

Heat shrink tubing of this type is typically installed by electricians and wiring technicians using a heat gun set to the appropriate shrink temperature for the FP-301 series. De-energize all circuits before applying shrink tubing to live conductors or connections. Avoid using an open flame, as uneven heat distribution can damage the tubing or underlying insulation. Ensure the tubing fully covers the intended splice or terminal before applying heat to achieve a complete, uniform shrink.
