A face plumbing adapter having a block portion and a camber portion is provided for a manifold of a heat exchanger assembly. The block portion includes an external planar face, a first mating surface opposite that of the planar face, and an aperture having a B-axis extending through the planar face and first mating surface. The camber portion extends integrally from the block portion in a direction away from the planar face and curving inward toward the B-Axis. The camber portion is biased toward the block portion such that the face plumbing adapter would clinch onto the manifold. The block and camber portions include respective mating surfaces that are complementary to the exterior surface area of the manifold onto which the mating surfaces are affixed.

A non pressurized internal separator leak test method is disclosed for a two pass condenser in which helium is injected below a vertical manifold tank separator, allowed to rise, and detected or not detected above the separator. The helium cannot reach the upper side of the separator other than through a separator leak path, because it will not flow sideways down the flow tubes.
