The Moroso 1/2-inch NPT weld-on bung is a single steel fitting designed to be welded into a tank or sheet metal to provide a threaded port. It creates a reliable, permanent 1/2-inch NPT access point for plumbing or component attachment, allowing builders to add a standard threaded connection where none existed before.
