Panduit HSTT400-48-2C Heat Shrink Tubing 4 Inch

Product Description

The PANDUIT HSTT400-48-2C is a thin-wall heat shrink tubing sleeve used for electrical insulation, bundling, and strain relief of wires and cable assemblies. At 4 inches (101.6 mm) in diameter before shrinking, this tubing is suited for large-gauge conductors, multi-conductor bundles, and industrial wiring applications. Thin-wall construction allows for faster heat application and a clean finished profile without excessive bulk. Electricians and industrial maintenance technicians reach for this product when a reliable, professional-grade insulation sleeve is needed on the job.

This heat shrink sleeve is appropriate for use in residential, commercial, and industrial electrical installations where wire protection, insulation, and abrasion resistance are required. Typical applications include splices, terminations, connector backshells, and cable harness finishing. The 4-inch diameter makes it well suited for large conduit runs, bus bar insulation, or heavy equipment wiring assemblies where standard small-diameter tubing would not fit.

Key Features

• 4-inch (101.6 mm) diameter thin-wall construction for large conductors and bundles
• Thin-wall profile enables faster shrink times and a lower-profile finished sleeve
• Provides electrical insulation, mechanical protection, and abrasion resistance
• Sold as a single unit (EA) for job-specific or repair use

Compatibility

Designed as an OEM-style heat shrink sleeving solution for large-diameter wire bundles, cable assemblies, and electrical terminations in commercial and industrial wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified maintenance technicians. De-energize and lock out all circuits before applying heat shrink tubing to any conductor or assembly. Use a calibrated heat gun set to the appropriate shrink temperature to achieve uniform shrinkage without scorching the tubing or damaging adjacent components. Follow applicable NEC requirements for insulation ratings and conductor protection in the installation environment.
