Abstract
According to one embodiment of the invention, a combination air vent/probe port includes an outer body adapted to couple to a conduit, the outer body formed with a longitudinal bore defining an inner wall, the longitudinal bore having a seating surface. The combination air vent/probe port also includes an inner sleeve adapted to adjustably engage the outer body, the inner sleeve having an outer diameter and formed with an inner chamber. Furthermore, a resilient member is disposed within the inner chamber, the resilient member operable to allow a probe to be inserted therethrough when the inner sleeve is adjustably engaged with the outer body and an end of the inner sleeve is engaged with the seating surface. The inner sleeve, when adjustably engaged with the outer body, is axially movable with respect to the outer body such that when the end of the inner sleeve is not engaged with the seating surface a flow passage is produced between the outer diameter and the inner wall, the flow passage operable to allow fluid media to escape from the conduit.
