Oleodinamica Marchesini G1050 GGL 1/4 in-line rotating coupling

Oleodinamica Marchesini G1050 (GGL 1/4) is an in-line rotating coupling for a 1/4" BSP hydraulic connection. The factory table lists a maximum flow of 25 l/min, a maximum pressure during rotation of 200 bar and a separate maximum pressure rating of 400 bar.

Installed between a flexible hose and a fixed component, the coupling compensates hose rotation and torsion to help prevent hose damage. The manufacturer explicitly excludes fast and continuous rotation. No permitted rotational speed is specified on the sheet. Apply the lower pressure limit when the joint is rotating.

The body is zinc-plated steel with low-friction seals. Connect the P ports as shown in the original drawing. This is the in-line arrangement, with a listed L1 dimension of 61 mm. Seal compound and a temperature range are not specified in the source.

The G-prefixed article is the standard BSP-threaded steel execution. The manufacturer lists NPT-threaded GN and stainless-steel GX versions on request; neither option is assigned to this exact article.
