3M 7000133626 Heat Shrink Tubing FP301 3/8 Inch Green

Product Description

The 3M 7000133626 is a thin-wall heat shrink tubing from the FP-301 series, designed to provide reliable electrical insulation, physical protection, and chemical resistance across a wide range of industrial and military applications. Supplied in a 48-inch length with a 3/8-inch diameter and finished in green, this tubing shrinks uniformly when heat is applied, forming a tight, conforming sleeve over conductors, splices, terminals, and wire bundles. Licensed electricians, military MRO technicians, and industrial maintenance professionals regularly use FP-301 series tubing for both new installations and field repairs where consistent performance is required.

This tubing is suited for applications where electrical insulation combined with protection against abrasion, moisture, and common industrial chemicals is needed. The green color supports color-coding of wire harnesses and circuit identifiers in control panels, equipment wiring, and military assemblies. At 48 inches per piece, it provides sufficient length for multiple terminations or a single long-run application depending on the cut length needed in the field.

Key Features

• Thin-wall FP-301 construction provides a balance of electrical insulation and flexibility
• 3/8-inch diameter accommodates a range of conductor and terminal sizes
• 48-inch length allows for multiple cuts per piece
• Green color-coding supports organized, code-compliant wire identification
• Suitable for industrial and military-grade applications requiring chemical and moisture resistance

Compatibility

Designed as an OEM-style replacement or standard supply component for industrial and military wire harnessing applications requiring thin-wall heat shrink sleeving in the 3/8-inch diameter range.

Installation Notes

Installation is performed by electricians and electronics technicians using a calibrated heat gun or approved heat source to shrink the tubing evenly over the substrate. De-energize and lock out all circuits before applying heat shrink sleeving to live conductors or terminals. Avoid open flame as a heat source, as uneven heat can cause improper shrinkage or damage to the tubing. Follow applicable NEC guidelines for conductor insulation and color-coding requirements in your jurisdiction.
