The present invention relates to hydrocarbon well fluid manifold module (1) with a manifold module housing (9) having a transversal bore terminating in a longitudinal bore (3) in fluid connection with the transversal bore (6). One or more cut off valves are located (7) in the transversal bore (6). The longitudinal bore (3) extend through the module housing (9) and form a first flow port (11) and a second flow port (12) aligned with the first flow port (11). Plane, connecting surfaces surround the two flow ports (11,12). The two flow ports and connecting surfaces are identical. The first connecting surface (13) and the second connecting surface (14) are adapted to be connected to at least one further similar manifold module (20). The invention also concerns a manifold for a hydrocarbon well assembled of such modules.
