Panduit HST3.5-48-2Y Heat Shrink Tubing Thick Wall

Product Description

The PANDUIT HST3.5-48-2Y is a thick-wall, adhesive-lined heat shrink tubing sleeve designed for durable environmental sealing and strain relief on wire and cable assemblies. The adhesive inner wall melts during shrinking to form a watertight bond around the conductor or connector, providing resistance to moisture, corrosion, and mechanical stress. This type of tubing is a standard component in electrical harness work, field splices, and termination protection across industrial, commercial, and residential wiring applications. Electricians and wire harness technicians install it wherever a sealed, high-integrity covering is required over conductors, splices, or connectors.

Adhesive-lined thick-wall heat shrink tubing like the HST3.5-48-2Y is used in control panel wiring, marine and outdoor electrical installations, automotive harness repair, and industrial cable management. The thick wall construction provides added mechanical protection compared to standard single-wall tubing, making it well suited for applications where abrasion resistance and environmental sealing are both required. It is sold as an individual piece per the supplier unit of measure.

Key Features

• Thick-wall construction provides mechanical protection and abrasion resistance beyond standard single-wall tubing
• Adhesive inner lining melts on shrink to create a watertight environmental seal around conductors and connectors
• Suitable for moisture-sensitive and outdoor electrical installations
• Sold individually, allowing single-piece procurement for repair and service work

Compatibility

Designed as an OEM-style replacement and general-use thick-wall adhesive heat shrink sleeve for wire and cable termination applications in electrical, industrial, and marine service environments.

Installation Notes

Installation is performed by licensed electricians or qualified wire harness technicians. De-energize and lock out the circuit before applying heat shrink tubing to any conductor or termination. Use a calibrated heat gun set to the appropriate shrink temperature to achieve uniform shrinkage and full adhesive flow without scorching the tubing. Installations in wet or outdoor locations should comply with applicable NEC requirements for environmental protection of wiring methods.
