Abstract
A method and apparatus for connecting air conditioning coolant lines. The apparatus comprises a coupler body, a coolant line, a flexible annular seal, a nut, and a deformable annular retainer. The coupler body has a passageway extending therethrough and a coolant line is disposed at least partially within the passageway. A flexible annular seal is disposed within the passageway in the coupler body for sealingly engaging the coolant line. The nut receives the coolant line therein and threadably engages the coupler body. A deformable annular retainer is disposed on the coolant line for engagement with the nut and the coupler body, wherein the threadable engagement of the nut with the coupler body urges the deformable annular retainer into a sealing engagement with the coupler body and the coolant line. The method includes swaging a deformable annular retainer to a coolant line, providing a nut on the coolant line, providing a coupler body having a passageway and a flexible annular seal disposed within the passageway, engaging the coolant line with the flexible annular seal to create a first seal, engaging the coupler body with the deformable annular retainer to create a second seal, and tightening a threaded engagement of the nut and the coupler body.
