Plastic Threaded Caps


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. The easy to grip head design on our UNF/JIC threaded cap allows for efficient installation and removal. This design is also available to cap Metric and BSP threads.

Our UNF/JIC threaded caps for fared/flareless fittings are made of blue LDPE and feature a rolled thread. This design allows you to thread or push on the cap for easy and efficient installation.

UNJ/UNJS threaded caps are available to fit tubing sizes from 3/16" to 1-1/2". Made of black HDPE these caps protect UNJ/UNJS threaded components from contaminants during production, storage, and shipment. The easy to grip head design allows for ease of hand installation.

Essentra quick fit caps for metric threads are made from red LDPE caps and designed with fewer thread forms for quick application and removal. Our quick fit caps fit metric threads from M8x1 to M30x2.

Protect and limit fluid leakage with Essentra UNF/Metric threaded sealing caps. The yellow HDPE material is 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.
