The CEC20-DUSTCAP is a plastic cap manufactured by Caplugs that is designed to protect exposed threads, valves, fittings, and machinery from dust and dirt. It can fit over the top of almost any exposed threads or other protrusions with a wide range of sizes and styles available to choose from. Made from durable polyethylene, the CEC20-DUSTCAP has a universal fit and helps guard against leakage, tampering, and contamination. It is also temperature resistant, so it can withstand hot and cold environments, and can be reused multiple times.
