3M 7000133612 Heat Shrink Thin-wall Tubing 3/4 in 48 in Black

Product Description

The 3M 7000133612 is a flexible polyolefin heat shrink thin-wall tubing designed for wire and cable insulation, bundling, and environmental protection in electrical installations. Supplied in a 48-inch length with a 3/4-inch nominal diameter, this tubing shrinks uniformly when heat is applied, creating a snug, protective sleeve over conductors, connectors, and terminations. Polyolefin construction provides reliable dielectric insulation and resistance to moisture, abrasion, and common chemicals found in field wiring environments. The black finish suits applications where UV exposure or low-visibility routing is a factor. Electricians and low-voltage technicians working in commercial and residential panels, conduit runs, and service equipment will find this a practical shop-stock item.

FP-301 series thin-wall tubing is suited for general-purpose electrical insulation and identification of wire harnesses, cable assemblies, and splices. Its flexibility makes it practical in tight routing situations and in equipment where vibration is present. The 48-inch cut length works for bench-prep applications before field installation, allowing technicians to pre-cut sleeves to required lengths before pulling wire or terminating connectors in panels, junction boxes, and control cabinets.

Key Features

• Flexible polyolefin construction for reliable dielectric insulation and moisture resistance
• 3/4-inch nominal diameter thin-wall profile for wire and connector coverage
• 48-inch length allows on-bench pre-cutting to job-specific sleeve lengths
• Black color for UV-tolerant and low-visibility routing applications
• Uniform shrink profile reduces gaps and cold-flow at termination points

Compatibility

Designed as a general-purpose OEM-style heat shrink sleeve suitable for wire insulation, splice protection, and cable bundling in residential and commercial electrical wiring applications.

Installation Notes

Heat shrink tubing is installed by licensed electricians or qualified low-voltage technicians in accordance with NEC guidelines for insulation and termination requirements. De-energize all circuits and verify zero voltage before sleeving conductors or splices. Apply heat evenly using a heat gun set to an appropriate temperature range, moving the gun continuously to avoid burning or uneven shrinkage. Do not use an open flame as a heat source, as it can scorch the tubing and compromise insulation integrity.
