3M 7000133551 Heat Shrink Tubing FP301 1/4 in 48 in Black

Product Description

The 3M 7000133551 is a thin-wall heat shrink tubing from 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 diameter and finished in black, this tubing delivers a balanced combination of electrical insulation, physical durability, and chemical resistance. It is suited for a wide range of industrial and military-grade wiring applications where a dependable, low-profile heat shrink solution is required. Licensed electricians, panel builders, and MRO technicians are the primary installers.

The FP-301 thin-wall tubing is commonly used in industrial control panels, military and aerospace wire harnesses, and general-purpose electrical assemblies where moisture resistance and mechanical protection are needed. Its black finish makes it appropriate for applications requiring UV-stable or color-coded sleeving. The 48-inch stick length allows technicians to cut custom lengths on the job without waste.

Key Features

• Thin-wall construction provides a low-profile fit over wire bundles and terminals
• 48-inch length allows field-cutting to required dimensions
• 1/4-inch nominal diameter suits a range of wire gauges and connector boots
• Black finish suitable for UV-exposed or color-coded wiring installations
• Balanced electrical, physical, and chemical properties for industrial and military use

Compatibility

Designed as an OEM-style heat shrink sleeving solution for industrial and military wire and cable assemblies requiring thin-wall polyolefin tubing in a 1/4-inch diameter.

Installation Notes

Heat shrink tubing of this type is installed by electricians and wire harness technicians using a heat gun set to the appropriate shrink temperature. De-energize all circuits before applying tubing to any live wiring. Avoid open flame as a heat source, as uneven heating can damage the tubing or underlying insulation. Follow applicable NEC guidelines for insulation and sleeving in electrical enclosures.
