Quadrios 25CA729 liimapinnoitettu lämpökutistesukka 16mm 4mm:iin, 4:1, musta, 5m

Protect and seal electrical connections from moisture, corrosion, and mechanical stress with this adhesive-lined heat shrink tubing. When heated, the inner hot-melt adhesive melts and flows, creating a waterproof barrier while the outer polyolefin shrinks tightly around the joint. The 4:1 shrink ratio allows the tubing to conform to irregular shapes, making it ideal for cable splices, connector transitions, and repairs in demanding environments.

Who is it for

Electricians, automotive technicians, and marine installers who need reliable insulation and sealing for wire splices, terminations, and harnesses. Suitable for both indoor and outdoor use where moisture resistance is required.
