Bought new suction line for A/C. New hose had three o-rings where as old hose had two o-rings. The metal pipe diameter was the same size. Condenser fitting was same size. Napa store guy stated this was a direct fit. Pulled vacuum, leaked test, and found leak at the o-ring connection. Do I use thicker o-rings?
