Manifold End Piece Set w/ Drain and Vent
Mfr Part#: SSM402
Replacement end piece (air vent + drain valve set) for SSM/BSM series radiant heat manifolds. Includes manifold tee with pre-installed 3/8" automatic air vent and a 1/4-turn drain valve with garden hose threads and a cap.
End pieces are included with every manifold set and do not have to be purchased separately, unless replacement or a modification to the manifold is required.
My SSM104 manifold came with only one of these on it. I see that some of the other manifolds have two. Is there any good reason other than having a spare to add another to my manifold?

This piece goes onto the PEX manifold which is positioned higher (normally the return manifold). Only (1) air vent is needed for the manifold, and therefore, the 2nd SSM402 is not required.
