Reusable tube piercing tool for refrigerant recovery
A refrigerant tube piercing tool is described capable of being removably and sealingly mounted on a refrigerant tube of copper or the like in a sealed refrigerant system to enable the recovery of refrigerant from the sealed system without discharge into the atmosphere. The tool includes a pair of clamp members one of which includes a sealing member and passageway combined with a threaded, pointed piercing member that is manually threaded into engagement with the tube for forming a hole therein and a fitting having a Schrader valve incorporated therein to which a hose leading to a recovery tank can be connected to enable refrigerant to be transferred into the recovery tank for subsequent use. The tool is reusable and can be removed after the refrigerant has been transferred into the recovery tank in order that the leak or other problem with respect to the refrigerant system can be repaired at which time the hole formed in the tube is closed by soldering or the like with the refrigerant system then being recharged. 5 figs.
