Oleodinamica Marchesini R1320 OCN 1/4 conical banjo fitting

Oleodinamica Marchesini R1320 (OCN 1/4) is a zinc-plated steel conical banjo fitting for valve mounting. Its banjo eye diameter is 13.3 mm, catalogue dimension L is 14 mm and listed mass is 0.03 kg.

The factory table identifies the V end as G 1/4 under the heading gas conica (conical gas thread). The nominal size is 1/4 inch. The source does not establish an ISO thread standard or sealing angle, so neither is assigned here. The 13.3 mm banjo eye is an unthreaded mounting bore, distinct from the V-end thread.

This OCN row has no 12L or 15L tube designation. The shared sheet associates pressure ratings with those tube sizes; a row-specific pressure rating is therefore not assigned to this conical article.

Orient the fitting during installation, fit the tube or connection as shown in the applicable factory drawing and secure the banjo with the matching hollow screw. The stated 360-degree adjustment concerns assembly orientation; this is not a fast or continuously rotating hydraulic joint. No custom /M length code is generated.
