Heat shrinkable cable end caps

Heat shrinkable cable end caps are a type of heat shrink tubing used to seal cable ends. The end cap shrinks when heated. Heat shrinkable cable end caps contain adhesive, which ensures a proper seal when the cap is shrunk onto a cable end. This prevents moisture and dust from reaching the cable end. 

Our HSEC heat shrink cable end caps are ideal for low-voltage applications. They are UV and weather-resistant and comply with RoHS standards. 

Made of crosslinked polyolefin, they have an operating temperature range of -55 °C to +110 °C. The minimum full shrink temperature is 120 °C. These end caps are not flame-retardant or self-extinguishing and cannot be printed on. They are always black and halogen-free. The black color also contributes to their UV resistance. Heat shrink end caps are available with an inner diameter after shrinkage ranging from 4 to 82 millimeters.

Heat shrinkable cable end caps are used to seal the open ends of cables. This is done by shrinking an end cap around the cable end. Here's how: 

Step 1: Determine the diameter of the cable and select a heat shrinkable cable end cap with a post-shrink diameter slightly smaller than the cable diameter. For example, if the cable has a diameter of 6 millimeters, choose an end cap with a post-shrink diameter of 5 millimeters.

Step 2: Place the heat shrinkable cable end cap over the cable end and evenly heat it with a heat gun. Our end caps have a minimum shrink temperature of 120 °C.
