Replacing Lines/Fittings

NOTICE: It is essential to tighten all tubing connections to the specified torque for the type and size of the tube fitting. When tightening steel-to-aluminum connections, the torque specified for aluminum must be used. Insufficient or excessive torque when tightening can result in loose joints or deformed joint parts. Either condition can result in refrigeration leakage and an inoperative air conditioning system. Refer to specifications.
