Claim Text:
1. A port fitting for insertion in a port hole in a flow module or flow plate, the port fitting comprising: a head configured to extend outwardly from the port hole; a shaft having a central axis, the shaft extending from the head to a terminal end of the shaft and being configured to extend axially into a flow channel in fluid communication with the port hole; the shaft defining a first portion and a second portion located radially inward from the first portion, the first portion defining a fastening element thereon for fastening the port fitting in the port hole, the first portion defining a first portion diameter extending axially inward from the fastening element and corresponding to a first port hole diameter, the second portion defining a second portion diameter extending axially inward from the first portion corresponding to a second port hole diameter, the second portion diameter being less than the first portion diameter thereby forming a first portion annular lip positioned against a corresponding port hole annular lip, the second portion terminating in a second end defining one of a tapered tip or an arcuate tip, the second end of the second end portion defining a free axial end of the shaft; an annular groove formed in the second end of the second portion, the groove facing axially away from the head and the groove defining an axial depth; an annular seal arranged in the groove radially inward from an exterior surface of the second end of the second portion, the seal having a cross sectional diameter that is of a greater magnitude than the axial depth of the groove, so that a portion of the seal protrudes from said groove and the terminal end extending axially inwardly into the port hole beyond the annular groove; and the seal together with the port fitting being configured to seal the port hole from fluids flowing in the flow channel.
