ABSTRACT:
An end cap is provided for adjacent pipes in the cooling coils of an electric air furnace. Each end cap includes parallel opposite side walls and a curved end portion connecting the side walls. The side walls and end portion define a perimeter edge, the outer portion of which is beveled. The end cap includes a pair of tabs extending from each side wall. The tabs partially fill the crevice between adjacent end pipes so as to provide a stronger weld between the end cap and the pipes. The curvature of the end cap minimizes turbulence of the liquid coolant flowing through the pipes.
