4:1 Shrink Ratio Adhesive Lined -55°C to 125°C

W-1-SB(4X)GR High-Shrink-Ratio Adhesive-Lined Semirigid Polyolefin Tubing

4:1 shrink ratio allows a few sizes to cover a wide range of splice and component diameters. Mechanically tough tubing provides strain relief and abrasion protection of wire splices, terminals, and other components. Adhesive-lined against fluids, moisture and other contaminants.

4:1 Very high shrink ratio

Longitudinal shrink ratio: ≤+8%

Outer jacket flame retardant, inner adhesive self-extinguished

Continuous operating temperature: -55°C to 125°C

Shrink temperature: 120°C
