Threaded Caps

Plastic caps with threads for product and component protection

Plastic threaded caps and plugs are used to protect or seal threaded components in industries such as automotive, machinery manufacturing, aerospace, oil and gas, electronics, and construction. The plastic caps and plugs protect components from damage caused by contamination and accidental damage while extending their lifespan.

We offer an extensive range of plastic threaded caps and plugs in various sizes, colours, and specifications. Due to the high quality and precision manufacturing of our plastic threaded caps, we can ensure a tight fit while making them easy to install and remove.

Applications and use cases

Electronics manufacturing: Threaded end caps protect connectors, terminals, and other sensitive electronic components during assembly, shipping, or storage.

Automotive: Plastic threaded caps shield various automotive components from potential contamination or accidental damage during the manufacturing process.

Furniture manufacturing: End caps prevent damage to threaded joints and components during production, assembly, and shipping.

Industrial equipment: To cover and protect exposed parts of machinery or equipment during manufacturing, maintenance, or transit, a plastic threaded plug can be used.

Gas and oil: Make it easy to open and close a closed circuit while still ensuring that the seal is reliable and safe with pipe end caps for gas fittings.

Aerospace: Benefit from Caplugs’ decades of experience in meeting the special geometries and materials requirements for protecting electronics and precision mechanics in the aerospace sector.
