Abstract
A T-shaped fitting for a port in the wall of a closed fluid system includes a branched tubular body having a proximal end coupled to the wall in fluid-tight communication with the port and two distal ends and defining passages between the proximal end and each of the distal ends. A flexible resilient membrane closes one of the distal ends and has a normally closed slit therein adapted for removably receiving an associated probe therethrough in sealing engagement therewith, while an insect screen is disposed across the other of the distal ends. Caps, tethered to the body, are respectively threadedly engageable with the distal ends. Two elastomeric seals are provided between one of the distal ends and its cap, channel means being provided in that one distal end to permit venting when the cap is partially removed. The other cap is sealed by means of a tapered thread.
