Quadrios 25CA497 Adhesive-Lined Heat Shrink Tubing, Transparent, 6.4 mm to 2.1 mm, 1 m

Electrical connections exposed to moisture, corrosion, and mechanical stress often fail prematurely. Quadrios 25CA497 heat shrink tubing with adhesive lining creates a durable, waterproof seal that insulates and protects splices, terminals, and cable joints in demanding environments.

Who is it for

Electricians, automotive technicians, and maintenance professionals who need reliable insulation and sealing for wire connections in vehicles, marine applications, outdoor installations, and industrial equipment.
