ABSTRACT:
A pressure connector is used to temporarily connect a pressure head with a device to be tested under pressure. The pressure head engages a flat surface around an opening and seals against it without any leakage. The pressure head includes a seal head with a seal therein for engaging the flat surface of the device to be tested. The seal head is moveable axially in either direction for a limited distance on an arbor. Suitable compression springs permit the seal head to adapt to slight differences in stroke requirements as the pressure head is used with different parts to be tested. The test pressure, preferably air pressure, is introduced and acts on the seal head and the cup-like seal in the seal head, urging the seal head and the seal into full surface sealing engagement with the flat surface around the opening into which the test pressure is to be introduced into the device being tested. Upon completion of the test pressure step, the mechanism applying a location force to the pressure head arbor for beginning the cycle is removed and the test pressure acting on one end of the arbor moves the arbor to its retracted position. The test pressure is then vented and the device being tested is removed.
