Panduit HSTT50-48-Q1 Heat Shrink Tubing 0.50 in 25pc

Product Description

The PANDUIT HSTT50-48-Q1 is a thin-wall heat shrink tubing pack used to insulate, protect, and bundle electrical conductors, splices, and terminations. Designed for use in wiring harnesses and electrical assemblies, this tubing shrinks when heat is applied, forming a tight, protective sleeve over connections. The 0.50-inch diameter size suits a wide range of conductor and connector sizes commonly encountered in commercial, industrial, and trade electrical work. Each pack contains 25 pieces, making it practical for repeated use across a job or for stocking a service van.

This heat shrink tubing is suited for electricians, panel builders, and low-voltage installers working on control panels, motor wiring, instrumentation leads, and field splices. The thin-wall construction keeps the finished profile compact while still delivering reliable insulation and strain relief. It is commonly used in environments where conductors need protection from abrasion, moisture, and incidental contact.

Key Features

• Thin-wall construction keeps finished diameter low after shrinking
• 0.50-inch supplied diameter fits a broad range of conductors and terminals
• 25-piece pack supports repeated use on multi-connection jobs
• Shrinks uniformly when heat is applied with a heat gun or torch
• Suitable for insulation, bundling, and splice protection in electrical assemblies

Compatibility

Designed as an OEM-style heat shrink sleeve for use on electrical conductors, terminals, and splices requiring a 0.50-inch nominal diameter thin-wall tubing in standard 48-inch lengths or pre-cut segments.

Installation Notes

Heat shrink tubing is typically installed by licensed electricians or low-voltage technicians following applicable NEC guidelines. De-energize all circuits before applying tubing over live conductors or terminations. Apply heat evenly along the length of the tubing using a calibrated heat gun, working from the center outward to avoid trapping air. Do not use an open flame directly on the tubing, as uneven heat can cause incomplete shrink or damage to the insulation.
