Oleodinamica Marchesini R1250 long banjo pipe

Oleodinamica Marchesini R1250 is a long banjo pipe for direct cylinder mounting of the DIN 2353 valve family. Its exact OL row gives length 199 mm, eye bore 17 mm and a 12 mm tube outside diameter. The nominal eye designation 3/8 identifies the catalogue size; it is not presented as a threaded port in the smooth-bore banjo eye.

The factory family assigns 350 bar working pressure and 1000 bar burst pressure to the corresponding 12L tube execution. Burst pressure is a separate destructive-limit reference, not a working-pressure limit. The original row mass is 0.11 kg and banjo height is 17 mm.

The zinc-plated steel pipe can be oriented during assembly to set the valve-to-cylinder arrangement. The manufacturer describes 360-degree mounting adjustment; this is not a continuously rotating swivel under operation. Fit the pipe into the valve connection and secure the eye with the specified hollow bolt. Bolt, sealing details and assembly dimensions must match the exact interface.

The local technical PDF retains the complete relevant original manufacturer spread, including the size table, option legend, hydraulic circuit and drawing. Neighbouring executions apply only to their identified rows. Oil temperature 50 °C and viscosity 30 cSt shown beside curves are reference conditions.
