ABSTRACT:
A disconnect tool for disconnecting a tubing end from a fitting. The disconnect tool comprises a first member having a first front portion, a first rear portion, a first middle portion and a first channel disposed through the first front portion, the first rear portion and the first middle portion. The disconnect tool further comprises a second member having a second front portion, a second rear portion, a second middle portion and a second channel disposed through the second front portion, the second rear portion and the second middle portion. The second channel aligns with the first channel wherein second middle portion contacts an outer collet surface of the collet such that the second middle portion forces the outer collet surface against a forward end of the fitting to axially drive the collet inwardly against the fitting in order to release the tubing end from the collet.
