Oleodinamica Marchesini R1340 conical banjo fitting

Oleodinamica Marchesini R1340 is a conical banjo fitting identified by the exact OCN 1/2 factory row in the earlier manufacturer sheet retained by the supplier. It is an eye fitting for the DIN 2353 valve-mounting arrangement, with an indicated eye bore of 21.2 mm and length reference L of 21 mm.

The original row prints G 1/2" under the column headed “gas conica”. Because the G designation and the conical-thread heading are not consistent enough to assign one thread standard, the original notation is retained as a text reference. No unqualified BSP or BSPT port filter is assigned.

The family material is zinc-plated steel. The sheet pressure references of 350/280 bar working and 1000/780 bar burst are explicitly associated with 12L/15L tube executions; they are not assigned to this separately listed OCN 1/2 part. Its row mass is 0.10 kg. The current OCN download lists smaller OCN sizes and does not individually settle the lifecycle or rating of R1340; a current exact supplier offer and the original row support this profile.

The local PDF preserves the relevant original manufacturer pages and exact article or accessory drawing. Neighbouring assemblies and options apply only to their identified rows. Any 50 °C oil temperature and 30 cSt viscosity shown beside curves are reference conditions, not general operating limits.
