Widely considered a standard threading protection option, NPT caps are common in a variety of applications, protecting threaded components for consumer, industrial and business use.

The NPT threaded caps available from Caplugs are designed to cover a wide range of threaded endings, including standard NPT fittings, long threads on exposed well casing pin ends, threads for aerospace and military aviation applications and more.
