A fluid connection for reducing a volume in this connection is disclosed herein. The connection includes a first connector (19) having a first body (20) encircling a first bore (21), the first body having a first sealing surface (25) and a second connector (22) having a second body (23) encircling a second bore (24), the second body having a second sealing surface (26) to form a tight connection with the first sealing surface. The connection also includes a volume (17) between the first and second connector and a protrusion (28) in one of the first and second body. The connection further includes a cavity (29) in a remaining one of the first and second body and which cavity is receiving the protrusion separating the volume into a first volume (30) and a second volume (31), which is at a distance from the first volume.
