Push-and-pin style completion plugs simplify the completion procedure by eliminating the possibility of a cross-threaded completion plug and the need to perform a “dry run.” Additional benefits of using a push-and-pin style completion plug include: reduced installation time, simplified re-stopping, and standard size completion plugs (4″ to 8″ fittings share a common size completion plug; 10″ and 12″ fittings also share a common size completion plug).
