Caps, Plugs & Masking

Guard pipes against contaminants, protect vital components during shipment and storage, and mask threads during finishing processes with our protective plastic caps and plugs. Most Essentra standard caps and plugs are in stock and ready for same day shipping.

While it is common for the terms cap and plug to be used interchangeably, protective caps slide or twist over the end, fitting the outside diameter of the pipe, while protective plugs are inserted inside, fitting the inside diameter of the pipe end.

We offer a selection that includes standard push fit and threaded styles, as well as many specialized types, such as flange covers, hydraulic caps and plugs, bolt and screw caps, and paint masking products. Our range includes caps to fit UNF, JIC, Metric, and BSP threads with an easy to grip head design for efficient installation and approval.
