This 120-piece heat shrink tubing assortment includes pre-cut 3-inch lengths designed for insulating wire splices, solder connections, and component leads in vintage electronics. The set includes six internal diameters from 1/16 inch to 3/8 inch, providing coverage for fine-gauge tone arm wiring up to larger transformer taps and power wiring.

When heated, the tubing contracts to form a secure, non-conductive sleeve over bare connections to prevent electrical shorts and provide strain relief. It is suitable for recapping, rewiring, and mechanical repairs in mid-century tube radios, gramophones, and automatic record changers manufactured by companies such as Philco, Zenith, RCA Victor, Garrard, and Voice of Music (V-M).
