3M 7000133609 Heat Shrink Tubing FP301 1/2 in 48 in Clear

Product Description

The 3M 7000133609 is a clear, thin-wall heat shrink tubing from the FP-301 series, designed to provide reliable electrical insulation and mechanical protection across industrial and military-grade applications. Supplied in 48-inch lengths with a nominal recovered diameter of 1/2 inch, this tubing delivers a strong combination of electrical, physical, and chemical resistance properties. It is commonly installed by electricians, harness builders, and maintenance technicians to protect wire terminations, splices, and bundled conductors from abrasion, moisture, and contaminants.

FP-301 thin-wall heat shrink tubing suits a broad range of installation environments, including panel wiring, field service repairs, and production assembly in industrial and military settings. The clear jacket allows visual inspection of the underlying conductor or splice after installation, which is useful during inspection and quality control workflows. Each piece ships as a single 48-inch section, making it easy to cut to required lengths on the job.

Key Features

• Thin-wall construction for low-profile insulation with minimal added diameter
• Clear jacket allows post-installation visual inspection of conductors and connections
• 48-inch length provides flexibility to cut to job-specific dimensions
• Suited for both industrial and military application environments
• Balanced electrical, physical, and chemical resistance properties

Compatibility

Designed as an OEM-style replacement and general-purpose heat shrink sleeve for wire insulation, termination protection, and splice covering in industrial and military wiring applications.

Installation Notes

Installation is typically performed by licensed electricians or qualified wiring technicians. De-energize all circuits before applying heat shrink tubing to any conductor or termination point. Use a calibrated heat gun rather than an open flame to apply uniform heat and achieve consistent shrink without damaging the tubing or adjacent components. Follow applicable NEC requirements for the circuit type and environment being serviced.
