Unified Thread Caps

Caps for unified and unified special threads
Unified threading is used across the United States and Canada, and a common choice for connectors and fasteners used in many different applications. Caplugs’ DC series of caps are designed to protect these threaded components and parts, preventing damage or unwanted soils from impacting your finished item.

These unified threaded caps are designed to be either threaded or pushed on with ease, using rolled threading that provides a perfect fit to match the size of your part connection. These caps are made from high-density polyethylene and designed to meet UN and UNS specifications, making it easy to meet your standard threaded design.

Unified threaded caps are offered in blue as a standard option, and available in standard carton, micropack and minipack quantities. Place your order online now or contact our team for information on additional sizes or other customization options you need.
