Alpha Wire F2213/8-BK007 Heat Shrink Tubing 3/8 in 50 Ft

Product Description

The ALPHA WIRE F2213/8-BK007 is a black heat shrink tubing cut to a 50-foot length with a 3/8-inch diameter. Heat shrink tubing is a polyolefin or similar polymer sleeve that contracts radially when exposed to heat, forming a tight, protective layer over wire splices, terminals, connectors, and cable bundles. Electricians, HVAC technicians, and other trade professionals use it to provide insulation, strain relief, and environmental protection on conductors and connection points. The black color aids in UV resistance and blends into common wiring applications.

This tubing is suited for general-purpose wiring tasks in residential, commercial, and light industrial settings. Common applications include covering soldered wire joints, bundling multi-conductor cables, protecting terminal ends on control wiring, and marking or color-coding harnesses. At 3/8-inch diameter, it accommodates a range of wire gauges and connector bodies typical in low-voltage control circuits, motor leads, and panel wiring. The 50-foot spool provides enough material for multiple jobs on a single roll.

Key Features

• 3/8-inch nominal diameter accommodates a range of wire sizes and connectors
• 50-foot length provides material for multiple service calls or installations
• Black color offers UV resistance and suits general wiring applications
• Heat-activated shrink provides insulation and strain relief at splices and terminals
• Sold as a single unit for straightforward stocking and ordering

Compatibility

Designed as a general-purpose heat shrink tubing suitable for electrical, HVAC control wiring, and similar low-voltage and line-voltage wiring applications where 3/8-inch diameter sleeving is required.

Installation Notes

Heat shrink tubing is typically installed by licensed electricians or qualified HVAC technicians following NEC guidelines for wire insulation and connection protection. De-energize all circuits before applying tubing over conductors or terminals. Use a heat gun rather than an open flame to apply even, controlled heat that shrinks the tubing without damaging the underlying conductor or insulation. Avoid overheating, which can cause the tubing to split or lose its protective properties.
