3M 7010321005 FP301 Heat Shrink Tubing 2in Blue 48in 24pc

Product Description

The 3M 7010321005 is a thin-wall heat shrink tubing sold as a package of 24 pieces, each measuring 48 inches in length with a 2-inch diameter, in blue. Based on the FP-301 product line, this tubing is engineered to deliver a reliable balance of electrical insulation, physical protection, and chemical resistance. It installs by applying controlled heat to shrink the tubing tightly around conductors, splices, terminals, or components. Electricians, electronics technicians, and military MRO professionals use FP-301 tubing as a durable insulation and bundling solution across a wide range of industrial and military-grade wiring applications.

This tubing is suited for industrial and military wiring harness protection, terminal insulation, and conductor bundling. Its thin-wall construction allows it to conform closely to the underlying component once heat is applied, making it appropriate for applications where a low-profile finish is needed. The blue color supports color-coded wire management and circuit identification in complex wiring systems. It is commonly used in control panels, machine wiring, and field-service repair of electrical assemblies.

Key Features

• Thin-wall construction provides low-profile insulation after shrink
• Blue color supports color-coded wire identification and circuit organization
• Balanced electrical, physical, and chemical resistance properties
• Suitable for industrial and military wiring applications
• Each piece is 48 inches in length for versatile cut-to-length use
• Sold in a pack of 24 pieces for job-site or shop stocking

Compatibility

Designed as an OEM-style heat shrink tubing solution for industrial and military electrical insulation and wire management applications requiring a 2-inch thin-wall sleeve.

Installation Notes

Installation is performed by qualified electricians or electronics technicians following applicable NEC guidelines. De-energize all circuits before applying heat shrink tubing to any conductor or terminal. Use a calibrated heat gun to apply uniform heat along the tubing length, working from the center outward to avoid trapping air. Do not use an open flame, as uncontrolled heat can damage the tubing or underlying components.
