Specifically used with Heat Shrink Tubing at the end of Wires and Cables.

These Heat Shrink End Caps provide an easy and efficient way of sealing, insulating and shielding cable or wire ends.

The ideal heat shrink temperature for the end caps is around 275F (135C). Applying the heat shrink end cap can be simple and hassle-free. Its always good to make sure the cable or wire is clean and free of debris before you place the heat shrink end cap over the exposed end.

When it comes to durability these end caps rank very high in quality. When looking for that extra protection against damage and moisture, Heat Shrink Cable End Caps is the ideal solution.

Heat shrink end caps with release valves are used for sealing high voltage and pressurized cables and to release expanding gases created inside cables due to storage, transportation and climate changes.

This is a super product, I ordered one as a test for a end cap for wire loom. The item shrinks as specified and makes a great companion for the 1 inch white non slit wire loom. The item has a glue inside the first portion for a seal, and it seals good around protruding wires. Will buy more to finish my 24 strand Mega Tree. Service from Electriduct was excellent and I received my shipment in 2 days. Very pleased customer.

These caps are a welcome (wonderful) addition to anyone that wants a little extra protection for their "loomed" wiring projects or "heat-shrunk" cable leads. In addition to the added protection, the caps give your projects a cleaner more finished look. Highly recommended.

I want to give a big thanks to the staff at Electriduct for getting my order turned around so quickly for a requirement that came up suddenly on our project in Tulsa. The heat shrink caps worked fine, just as described by the salesperson's additional input. I was pleased with the quality and will look to Electriduct for future orders when required.
