3M 7000133630 FP301 Heat Shrink Tubing 1/16 in Clear 25 Pc

Product Description

The 3M 7000133630 is a thin-wall heat shrink tubing from the FP-301 series, designed to provide reliable electrical insulation, strain relief, and environmental protection for wire and cable assemblies. Each piece measures 48 inches in length with a 1/16 inch diameter and ships in a pack of 25. The clear jacket allows visual inspection of the underlying conductor or splice without removing the tubing. FP-301 is engineered to deliver a consistent balance of electrical, physical, and chemical resistance properties, making it a dependable choice for both industrial wiring and military-specification applications.

This tubing is well suited for insulating and bundling wire harnesses, protecting solder joints and terminals, and adding mechanical protection to cable entry points. Its thin-wall construction allows it to conform tightly to irregular surfaces upon heat activation. Electricians, aerospace and defense contractors, and field service technicians routinely use FP-301 series tubing in panel wiring, connector backshells, and general-purpose conductor insulation across industrial and mil-spec environments.

Key Features

• Thin-wall construction for low-profile insulation and tight conformance after shrinking
• Clear jacket allows visual inspection of the underlying conductor or connection
• 48-inch length per piece provides flexibility for cut-to-length field installation
• 1/16 inch recovered diameter suits fine-gauge wire and small-diameter conductors
• Balanced electrical, physical, and chemical resistance for industrial and military applications
• Sold in a pack of 25 pieces for job-site or shop inventory use

Compatibility

Designed as an OEM-style heat shrink solution for general-purpose wire insulation, splice protection, and strain relief in industrial and military wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified technicians following applicable NEC guidelines. De-energize all circuits before applying heat shrink tubing to any live conductor or terminal. Apply heat evenly along the length of the tubing using a heat gun, working from the center outward to prevent air pockets or uneven shrinkage. Avoid open-flame heat sources, which can damage the tubing or create uneven recovery.
