Adhesive Lined Cross-linked Polyolefin

Adhesive-Lined Cross-Linked Polyolefin Heat Shrink Tubing — DSG CPA-100 Motorsport Sleeving

The DSG CPA-100 Adhesive-Lined Cross-Linked Polyolefin heat shrink tubing is a professional-grade dual-wall product used throughout motorsport harness construction for environmental sealing, strain relief, and insulation at splice joints, wire end-seals, and connector cable entry points. The cross-linked polyolefin outer layer provides high-temperature resistance and mechanical durability, while the hot-melt adhesive inner lining flows into irregular surfaces when heated to create a watertight seal — the defining characteristic of adhesive-lined heat shrink versus standard single-wall alternatives.

Dual-Wall Adhesive-Lined vs Standard Heat Shrink

Standard single-wall heat shrink provides insulation and mechanical protection but does not seal against moisture ingress. Adhesive-lined dual-wall tubing provides environmental sealing as well — a critical difference in motorsport applications where harness sections are exposed to rain, wash-down water, fuel spray, and condensation. At splice joints in particular, adhesive-lined tubing is the correct specification because it seals the exposed conductor at both ends of the splice barrel, preventing moisture from tracking along the wire core into the harness interior.

Motorsport Harness Applications

CPA-100 adhesive-lined tubing is used at crimp splice joints for environmental sealing, at wire bundle end-seals where a harness passes through a panel, at connector strain relief points to protect the cable entry from repeated flexing, and at any harness entry or exit point requiring a watertight seal. It is the standard product for these applications in professional motorsport harness building.
