Quadrios 25CA505 Adhesive-Lined Heat Shrink Tubing Set, Transparent, 65 Pieces, 3:1 Ratio, 100 mm Lengths

Quadrios 25CA505 is a heat shrink tubing set with adhesive lining, providing waterproof and strain-relief protection for electrical connections. Unlike standard tubing, the inner adhesive melts during shrinking to create a sealed, durable bond. The set includes 65 transparent polyolefin tubes in ten diameters, each 100 mm long, with a 3:1 shrink ratio. This variety covers a wide range of wire and connector sizes, making it suitable for automotive, marine, and general electrical repairs.

Highlights

• Adhesive-lined for waterproof sealing
• Transparent tubing allows visual inspection of the connection
• 3:1 shrink ratio for a tight fit over irregular shapes
• 65 pieces in 10 sizes (pre-shrink diameters from 2.4 mm to 25.4 mm)
• Made of cross-linked polyolefin, resistant to chemicals and abrasion

In daily use

Select a tube slightly larger than the connection, slide it over, and apply heat. The tubing shrinks and the adhesive flows, encapsulating the splice. The transparent material lets you verify the bond. The set's assortment covers most common wire gauges, from small electronics to battery cables. Operating temperature range is -55°C to +125°C, with full shrinkage at 140°C.
