Panduit HSTT150-C4 Heat Shrink Tubing 1.5 Inches

Product Description

The PANDUIT HSTT150-C4 is a thin-wall heat shrink tubing with a 1.5-inch recovered diameter, designed for insulating, protecting, and bundling wire and cable terminations. Thin-wall construction allows for faster heat recovery and a lower profile sleeve compared to standard-wall alternatives. Electricians and low-voltage technicians install this tubing on conductors, splices, and connector boots to provide environmental protection and strain relief in both residential and commercial applications.

This heat shrink tubing is suited for use in electrical panel work, wire harnessing, and cable management installations. It applies wherever a clean, insulated sleeve is needed over a termination or splice point. The 1.5-inch expanded diameter accommodates a range of conductor bundles and connector bodies, making it a practical choice for general electrical service work across multiple system types.

Key Features

• Thin-wall design for faster shrink recovery and lower profile finish
• 1.5-inch expanded diameter fits a broad range of wire bundles and connectors
• Provides insulation and environmental protection at splice and termination points
• Sold as a single unit for targeted, job-specific use

Compatibility

Designed as an OEM-style replacement and general-use heat shrink sleeve compatible with standard wire terminations, splices, and connector boots requiring a 1.5-inch diameter tubing profile.

Installation Notes

Installation is typically performed by a licensed electrician or low-voltage technician. De-energize all circuits before applying heat shrink tubing to any conductor or termination. Use a heat gun set to the appropriate temperature for the tubing material — open flame is not recommended, as it can unevenly shrink the sleeve or damage surrounding materials. Ensure the tubing is positioned fully over the splice or termination before applying heat, and allow it to cool completely before restoring power.
