RP901012M is a steel 90° elbow for the European pump-flange arrangement with three fixing holes. The fluid connection is 1/2" BSP; the flange connection is a separate mounting interface.
The technical sheet lists a 30 mm flange size designation and includes three M6×20* mounting screws together with an O-ring designated 15.88 × 2.62. R2 in this document denotes the included screws, not another threaded fluid port.
The section drawing identifies dimensions D, H, I and L. Their numerical entries and the O-ring designation are retained as catalog data, while units not explicitly provided by the sheet are left unresolved. No working-pressure rating or pump-group compatibility is asserted for this elbow.
