Heat Shrink Tubing Services for Wire Harness Protection and Identification
As a specialized heat shrink tubing application provider, OurPCB delivers cable protection and identification solutions for wire harness and cable assembly applications. Heat shrink tubing provides insulation, strain relief, environmental sealing, and wire identification in a cost-effective, reliable package.
Our heat shrink capabilities include standard polyolefin, adhesive-lined dual-wall, and specialty materials for demanding applications. Aerospace and defense applications use MIL-DTL-23053 qualified tubing. Marine cable assemblies require adhesive-lined heat shrink for moisture protection in harsh environments.
Shrink ratios from 2:1 to 6:1 accommodate diverse cable sizes and transitions. Temperature-rated options span -55°C to +200°C for automotive engine compartment and industrial high-temperature applications. Flame-retardant materials meet railway and building code requirements.
Printed heat shrink provides permanent wire identification supporting testing and field service. Color-coded tubing aids assembly and troubleshooting. Our laser marking capabilities complement heat shrink identification with permanent barcode and text marking.
Integration with overmolding and potting provides complete environmental protection. ISO 9001 quality systems ensure proper material selection and application. Contact us to discuss heat shrink solutions for your cable protection, strain relief, and identification requirements.
Heat Shrink FAQ
Heat shrink tubing provides insulation, strain relief, environmental protection, identification, and bundling for wires and cables. When heated, it shrinks to conform tightly around the cable or connection.
Adhesive-lined (or dual-wall) heat shrink has a layer of hot-melt adhesive inside. When heated, the adhesive melts and seals to the cable, providing moisture and environmental protection in addition to mechanical protection.
We stock tubing with shrink ratios from 2:1 to 6:1. Higher shrink ratios accommodate larger variations in cable diameter or transitions between different sizes. 3:1 is most common for general use.
Yes, we can apply printed heat shrink markers and labels for wire identification. These are printed before shrinking and become permanent identification marks on the wire or cable.
