Abstract:
1. A method of pressing a seal against a thermal expansion valve housing to form a seal between air conditioner lines and the housing, the method comprising: arranging a first block portion of a dual joint block against a first conduit line and a second conduit line; coupling a second block portion of the dual joint block to the first block portion; arranging the second block portion against the first conduit line and the second conduit line such that the first conduit line is completely surrounded by a first aperture defined by both the first block portion and the second block portion, and such that the second conduit line is completely surrounded by a second aperture defined by both the first block portion and the second block portion; fastening the first block portion and the second block portion to a thermal expansion valve housing with a first fastener to press a seal between the dual joint block and the thermal expansion housing, the fist fastener inserted through a first bore of the first block portion, a second bore of the second block portion aligned with the first bore where the first and second block portions overlap, and inserted into the thermal expansion valve housing; and fastening the first block portion and the second block portion to the thermal expansion valve housing such that an inner surface of the first block portion and an inner surface of the second block portion both contact the thermal expansion valve housing.
