ABSTRACT:
A fitting for connection between two locations in a transfer system whereby fluid or gaseous substances pass from one point to another through the fitting. The fitting comprises a hollow cylinder, a hollow stem with an enlarged bullet-shaped head and slidably extending through the cylinder, a passageway providing an escape path of least resistance to leaks occurring between the bullet-shaped head and corresponding fitting in a unit into which it is placed and an annular depression at one end of the hollow cylinder, at which leaks can be detected and, if desired, a leak-test location label can be applied. The hollow stem includes a circumferential groove which is located adjacent to the annular depression, the combination providing a means for retention of leak-test solution.
