After searching for good original water manifold fittings, I gave up and made them new to match my single pair of originals exactly. These are cast in gray iron. Inlet elbows (bottom of cylinder jugs) are cast to accept the brass drain cock, while outlet elbows (top of cylinder jugs) are simply just elbows. You can use 1/2″ pipe fittings, but they just don’t have “the look”!

Inlet elbows (for drain cock): $58 each

Outlet elbows: $45 each
