With a spiral-wound core, these end caps form a permanent seal on the end of your crimped wire or cable without heat or tools. Slide them on, pull out the core, and they conform to the end of your connection, creating a seal that insulates and protects against water, dust, and abrasion. You may also know them as cold-shrink tubing end caps. They’re sometimes even used to seal the ends of pipes and wire rope.

Made of EPDM, these caps won’t become brittle from ozone or chemicals such as acids and alkalies. They also won’t fade in the sun.
