3/4" White Heat Shrink Tubing, 4 ft, 2:1 Thin Wall

Thermosleeve HST34W4 — 3/4" White 4ft 2:1 Thin Wall Heat Shrink Tubing

Thermosleeve HST34W4 is a 3/4" white, 4 ft length, 2:1 thin-wall heat shrink tubing designed to insulate and protect electrical splices, terminations, and cable bundles. When heated, the tubing reduces to approximately half its nominal diameter to create a tight, uniform sleeve that improves strain relief and creates a professional finished appearance. The thin-wall construction is intended for low-profile applications where maintaining a compact jacket is important. White color offers discrete coverage and is useful for cable identification or installations where aesthetics matter. This tubing is well suited for field repairs, OEM assembly, and maintenance tasks that require quick, reliable insulation. Its flexibility makes it compatible with common wire sizes and assemblies without adding bulk. The 4 ft length provides a practical quantity for on-site work and bench projects.

Cutting to length is straightforward and application is fast: position the tubing, apply heat with a standard heat gun or torch until the sleeve fully conforms, and allow it to cool for a secure fit. Because this product is thin-wall 2:1 tubing, it is commonly chosen where a low build-up of material is required while still delivering reliable electrical insulation.
