A removably mounted probe provides access to a fluid enclosure. The front end of the probe has a collar which seats on a beveled shoulder to position the probe relative to the fluid enclosure. The back end of the probe extends through a ball valve and a pair of fittings positioned end-to-end which are held together by a snap coupling. The collar acts to dampen backward movement of the probe when it is released and finally abuts the fittings which limit the probe's movement. The ball valve is clo...
