Description

The PANDUIT HSTT38-T6 is a thin-wall heat shrink tubing designed for insulating, protecting, and bundling electrical conductors and connections. With a recovered diameter of 0.38 inches (9.5 mm), this tubing applies heat to shrink tightly around wire terminations, splices, and cable bundles, creating a durable insulating sleeve. It is a standard component in electrical and low-voltage wiring work, used wherever conductors need mechanical protection or clean termination. Electricians, instrumentation techs, and panel builders reach for thin-wall heat shrink when a low-profile, reliable insulation layer is needed without the bulk of adhesive-lined variants.

This tubing is suited for residential, commercial, and light industrial electrical installations. Common applications include wire harness assembly, terminal insulation, splice protection, and cable identification. Thin-wall heat shrink is a go-to material for panel wiring, conduit terminations, and field repair of wire insulation where a neat, professional finish is required. It is sold as an individual piece (each unit), making it practical for targeted repair work or small-quantity jobs.

Key Features

0.38 inch (9.5 mm) recovered diameter for a snug fit on common wire gauges
Thin-wall construction provides insulation without excess bulk
Shrinks uniformly when heat is applied, conforming tightly to the conductor or termination
Suitable for wire insulation, splice covering, and mechanical protection in electrical assemblies
Sold individually for flexible quantity purchasing on repair and service jobs

Compatibility

Designed as a standard thin-wall heat shrink sleeve for general electrical wire and cable insulation applications. Compatible with conductors and terminations where a 0.38 inch recovered diameter provides adequate coverage.

Installation Notes

Installation is typically performed by licensed electricians or qualified wiring technicians. De-energize all circuits before working on any conductors or terminations. Slide the tubing over the conductor or splice before making the final connection, then apply a heat gun evenly along the length of the tubing to achieve uniform shrinkage. Avoid applying direct flame, as uncontrolled heat can damage the tubing or adjacent insulation.
