Protecting your electrical connectors cannot be taken lightly, which is why Alliance Express has designed an entire product line of connector caps and plugs.
Our circular connector caps are manufactured in a red color, while the plugs are yellow. They are both designed for easy assembly and removal either with automated equipment or by hand. These caps and plugs are typically used to protect electrical connectors per Mil Spec 90376. We also carry a line of USB caps to provide a protective dust cover to your ports.
