Unified Thread Plugs

Plugs for unified thread and unified special threads

Caplugs unified thread and unified special thread plugs are commonly used in hydraulic, aircraft and automotive equipment, protecting parts and preventing exposure from environmental contaminants during production, transport and storage.

These thread plugs come in several options, with our DPN series featuring rolled threads that allow for plugs to be either pushed or threaded in for a consistent and solid barrier. They also offer external ribs for easy installation and removal, while being flanged to create a tight seal. They meet both UN and UNS specifications, making it easy to find the right fit for your components.

Caplugs also manufactures universal pull plugs with a flexible pull tab and a unified plug featuring a thick flange. Each offers ease in installation and removal.

Plugs are made with low-density or high-density polyethylene, depending on the specific series, providing options to suit different specific end applications. Choose from a wide range of sizes to meet your needs, with additional sizing and coloring options available through custom ordering.
