Description

The PANDUIT HSTTV38-T is a thin-wall heat shrink tubing rated to the VW-1 flame resistance standard. It is designed to provide insulation, strain relief, and environmental protection for wire terminations, splices, and cable bundles in electrical and low-voltage wiring applications. The tubing features a 0.38-inch recovered diameter, making it suitable for medium-gauge wire and cable runs. Electricians and wire harness technicians use this product where a clean, code-compliant insulation sleeve is required. The VW-1 flame rating confirms the tubing resists flame propagation, a key requirement in many panel and enclosure wiring scenarios.

This heat shrink tubing is used in residential, commercial, and light industrial electrical work. Typical applications include insulating butt splices, protecting terminal crimps, bundling control wiring inside panels, and providing abrasion resistance on cable routing points. It is sold as an individual piece, making it practical for spot repairs and small-quantity installations alongside larger wiring jobs.

Key Features

VW-1 flame resistance rating meets common electrical code requirements for insulation materials
Thin-wall construction allows the tubing to shrink down snugly without adding excessive bulk
0.38-inch recovered diameter fits medium-gauge conductors and terminal assemblies
Provides insulation, moisture resistance, and mechanical protection at wire terminations
Sold individually for flexible quantity purchasing on service and repair calls

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeve suitable for standard electrical wire insulation and termination protection tasks where a VW-1-rated material is specified.

Installation Notes

Installation requires a heat gun or similar controlled heat source to activate shrink; open flame tools are not recommended as they can damage the tubing or underlying insulation. De-energize and lock out all circuits before working on wiring connections. Slide the tubing over the conductor or splice before making the final termination, then apply heat evenly along the length for a uniform seal. Work performed in electrical panels or enclosures should comply with applicable NEC requirements.
