Description

A 4" black iron plug. It blanks a 4" outlet on a heating main or a manifold, either permanently or while a section is pressure tested in isolation. At 4" the plug itself is heavy enough to be worth supporting while it is started, since cross-threading one of these is an expensive mistake on a fitting of that size.
