ABSTRACT:
A tubing disconnect tool and a method of disconnecting tubing. A disconnect tool for disconnecting a tubing end which is inserted within a collet of a fitting comprises a first plate member, a second plate member and bias member. The first plate member has a first front portion, a first rear portion and a first middle portion. The first plate member further has a channel disposed within the first middle portion. The second plate member has a second front portion, a second rear portion and a second middle portion. The second plate member also has a second channel disposed within the second middle portion. The bias member connects together the first plate member and the second plate member such that the bias member spaces the first plate member to attach to the fitting and spaces the second plate member to contact an outer collet surface of the collet wherein the first channel is configured to engage an engagement surface of the fitting and the second channel is configured to contact the outer collet surface in order to force the outer collet surface against the fitting to release the tubing end.
