Plastic Threaded Caps

Essentra supplies 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.

Protect flared and flareless fittings against dirt, dents, and moisture with Essentra caps to fit UNF, JIC, Metric, and BSP threads. UNJ/UNJS threaded caps are available to fit tubing sizes from 3/16" to 1-1/2" and used to protect UNJ/UNJS threaded components from contaminants during production, storage, and shipment. The easy to grip head design allows for ease of hand installation. Protect and limit fluid leakage with Essentra UNF/Metric threaded sealing caps which are resistant to chemicals and reduces shearing. The cap includes a gasket to limit fluid leakage. The hexagonal head enables the application or removal with a wrench or sock at low torques but it is recommended to tighten by hand.
