Quadrios 25CA489 Adhesive-Lined Heat Shrink Tubing, 3:1, White, 25.4 mm Diameter, 1.2 m Length

This Quadrios heat shrink tubing stands out with its integrated adhesive lining, which melts during shrinking to create a waterproof and strain-relieved seal. Unlike standard tubing, it is ideal for protecting connections in demanding environments where moisture and mechanical stress are concerns.

Highlights

• Adhesive-lined for waterproof sealing
• 3:1 shrink ratio for versatile sizing
• White polyolefin, halogen-free and flame retardant
• UV resistant for outdoor use
• Wide operating temperature range: -55 °C to +125 °C

In daily use

With an inner diameter of 25.4 mm before shrinking and 8.5 mm after, this tubing accommodates a variety of cable and connector sizes. The 1.2 m length provides ample material for multiple applications. Simply slide over the connection, apply heat above 110 °C, and the tubing shrinks while the adhesive flows to seal out moisture and contaminants.
