An apparatus for sampling or feeding a flowable material through a wall of a vessel or conduit includes a body having a collection chamber formed therein. A passage has an opening operatively connected to the collection chamber. An orifice is formed in the body and is in communication with the collection chamber. The orifice is located generally adjacent the opening of the passage. A sealing device is mounted to the body to seal and unseal said orifice. Furthermore, at least a portion of the opening of the passage is located flush with or on a process side of the wall of the vessel or conduit when the apparatus is mounted to the wall of the vessel or conduit.
