Blue Tapered Cap Plug, #35

The Blue Tapered Cap Plug, #35, from Essentra Components is a small but useful accessory for water-treatment installations and equipment assembly. Tapered cap plugs serve double duty: they cap and seal the ends of pipes, ports, and fittings, and they protect threaded or machined surfaces from dust, debris, and damage during shipping, storage, or staging before final connection. Despite their low cost, parts like these prevent the kind of contamination and thread damage that can turn into expensive problems later in an installation.

The tapered design allows a single plug size to fit a range of openings, wedging snugly into place for a secure, friction-held seal that is still easy to remove when you are ready to make the connection. The bright blue color makes these plugs easy to spot, so a temporary plug is never overlooked during commissioning and accidentally left in a line. As a #35 size, this plug is intended for the specific opening dimensions that size designation covers, ensuring a proper fit without the guesswork of trial and error.

Whether you are protecting unused ports on a control valve, masking openings during a media change, or keeping debris out of fittings on the workbench, these tapered cap plugs are an inexpensive way to safeguard your components. Installers and assemblers often keep an assortment of sizes on hand for exactly these reasons, since the right plug is always handy when needed and a plugged port is far cheaper than a contaminated valve. Because the plugs are reusable, a single batch can protect parts through multiple service visits, and the soft, flexible material grips without scratching the surfaces it covers. They are equally at home in a fabrication shop sealing ports on assembled manifolds, on a service van keeping spare valves clean, or in a warehouse protecting inventory from dust during long-term storage. The Essentra #35 blue cap plug offers a reliable, reusable solution for capping and protecting the openings common in water-treatment plumbing and equipment.
