Abstract

The flange adapter attaches to the flange of a housing such as a bowl. The flow line attaches at the flange of the housing. The flange adapter attaches at the flange of the bowl to enable attachment of flow lines of multiple sizes to the bowl. The flange adapter includes an attachment body that secures to the bowl and an attachment neck that is raised above the attachment body. The flange adapter provides a first set of attachment apertures for securing the flange adapter to the housing and a second set of attachment apertures for securing the flow line to the flange adapter.
