Easily Heatshrink Over Large Connectors & Plugs

Shrinkflex 4:1 heatshrink tubing is the most versatile of the heatshrink products. The very high shrink ratio allows the material to fit over very large plugs or connectors and shrink down tightly.


4:1 Shrinkflex is ideal as a strain relief on assemblies that are subject to frequent connection cycles.

Shrinkflex® 4:1 Polyolefin

  • Shrinkflex® 4:1 Dual Wall Adhesive

    Dual wall adhesive lined heatshrink tubing is ideal for producing strong, weather tight seals on any heatshrink installation. During the application of heat from a heat gun or other hot air tool, the inner adhesive wall melts and flows, creating an adhesion layer to ensure a snug fit to your harness or connector.

    Shrinkflex adhesive lined heatshrink tubing has a 4:1 shrink  in 4' precut sticks.
