It’s the law in many places to cover the ports and test cocks on backflow assemblies. These plastic plugs make it easy and inexpensive. The SHP cap plugs keep dirt out of the ports on an assembly when no test cocks or other covers are present and they thread in nicely to provide an easy and secure fit.
3/4″ NPT plastic plug for test ports. Superior protection to press plugs. Approximately 50 per bag.
