It has a flange connection on one end designed to connect with another flange connection, or a compression type mounting pad. The other end has external and/or internal machine threads (straight threads other than pipe or hose series), and is designed to facilitate a gasket, preformed packing, washer, or the like, to form a seal at the boss. It may have side and/or heel inlet(s).
