Heat Shrink Caps - HSC016-500

Heat Shrink Caps – 148mm Max Internal Diameter – 57mm Shrink Internal Diameter – 152mm Internal Length - Black Polyolefin | Vital Parts – HSC016-500

All of our Heat Shrink End Caps are made from a high quality durable Polyolefin Thermoplastic. This material gives the caps their shrinking properties once heat is applied. Heat Shrink Caps are commonly used for insulation and sealing of broken or frayed cables where standard heat shrink tubing may not be required. They are suitable across a wide range of commercial and consumer applications.

What are Heat Shrink Caps?

Heat Shrink Caps are heat-activated end seals designed to cover, insulate or protect cable ends or small components. Once heated, the Polyolefin material shrinks to form a tight, durable seal. They are often used to prevent moisture ingress, electrical shorts or abrasion damage at cable terminations. Ideal where tubing is not practical, these caps offer quick and effective cable finishing.

This heat shrink cap has a maximum internal diameter of 148mm and will shrink down to a diameter of 57mm.
