3M 7000133607 Heat Shrink Thin-wall Tubing FP301 Clear

Product Description

The 3M 7000133607 is a thin-wall heat shrink tubing based on the FP-301 series, designed to provide reliable insulation, strain relief, and environmental protection for wire and cable assemblies. Supplied in a 48-inch length with a 1/4-inch nominal diameter and a clear finish, this tubing suits a broad range of electrical and industrial wiring tasks. Licensed electricians, MRO technicians, and military/aerospace wiring specialists rely on this product where consistent shrink performance and good dielectric properties are required in confined bundle geometries.

FP-301 thin-wall tubing is appropriate for general-purpose wire harnessing in residential and commercial electrical work, panel wiring, industrial control cabinets, and military equipment assemblies. The clear wall allows visual inspection of the conductor or connector underneath after installation, which is useful in quality-control environments and field verification situations. The 48-inch stick length works well for bench termination of individual conductors or short harness runs.

Key Features

• Thin-wall FP-301 construction balances flexibility with electrical insulation performance
• 1/4-inch nominal diameter accommodates a range of wire gauges and small connectors
• Clear tubing allows post-installation visual inspection of the underlying conductor
• 48-inch length suits bench-top termination and harness assembly workflows
• Suitable for industrial and military wiring applications requiring consistent shrink performance

Compatibility

Designed as an OEM-style replacement and general-use heat shrink tubing for wire and cable insulation applications across industrial, commercial electrical, and military assembly environments.

Installation Notes

Heat shrink tubing of this type is installed by licensed electricians and qualified wiring technicians following applicable NEC requirements. De-energize and lock out all circuits before applying tubing to conductors or connections. Use a calibrated heat gun set to an appropriate temperature range for thin-wall polyolefin tubing and apply heat evenly along the length to avoid scorching or uneven shrink. Do not use open flame for shrinking, as this can damage the tubing and surrounding insulation.
