Plastic Screw Plugs

A screw closure is a mechanical device which is screwed on and off of a "finish" on a container. Either continuous threads or lugs are used. It must be engineered to be cost-effective, to provide an effective seal (and barrier), to be compatible with the contents, to be easily opened by the consumer, often to be reclosable, and to comply with product, package, and environmental laws and regulations.

We supply a large selection of protection caps to protect threaded components. Our range includes sealing, quick fit, and valve caps to fit a variety of thread styles during transport and storage.
