Panduit HSTT25-48-Q3 Heat Shrink Tubing 0.25 Inch

Product Description

The PANDUIT HSTT25-48-Q3 is a thin-wall heat shrink tubing sleeve designed for electrical insulation, wire bundling, and strain relief in professional wiring applications. With a recovered diameter of 0.25 inches (6.4 mm), this tubing provides a clean, tight fit over conductors, terminals, and splices once heat is applied. It is a standard tool for electricians, panel builders, and low-voltage technicians who need reliable insulation and protection on finished wire terminations. The thin-wall profile keeps overall bundle diameter compact while still delivering consistent dielectric protection across the covered length.

This heat shrink tubing is suited for use in control panels, junction boxes, electrical enclosures, and field wiring applications where insulation and environmental protection of conductors or connections are required. It is commonly installed during termination work on commercial and industrial electrical systems. The 0.25-inch recovered diameter makes it appropriate for smaller gauge conductors and standard terminal connections encountered in low-voltage control wiring and general electrical work.

Key Features

• Thin-wall construction keeps bundle diameter low after recovery
• 0.25 inch (6.4 mm) recovered inside diameter for a snug fit on small conductors and terminals
• Provides electrical insulation and mechanical protection at wire terminations
• Suitable for wire bundling, splice coverage, and strain relief applications
• Single-piece unit sold individually for precise quantity control on the job

Compatibility

Designed as an OEM-style heat shrink sleeve for use on conductors, splices, and terminals requiring a 0.25-inch recovered inside diameter in standard electrical and low-voltage wiring installations.

Installation Notes

Heat shrink tubing is installed by licensed electricians and low-voltage technicians in accordance with NEC guidelines for insulation and termination protection. De-energize all circuits before applying heat shrink over live terminals or conductors. Use a heat gun set to the appropriate temperature for the tubing material — open flame torches are not recommended as they can damage the tubing or adjacent components. Slide the tubing into position before terminating the conductor where possible to allow proper placement prior to shrinking.
