Oleodinamica Marchesini GN1090 GGL 1 NPT in-line rotating coupling

Oleodinamica Marchesini GN1090 is an in-line rotating coupling in the GGL series, with 1" NPT connections. The exact article is explicitly offered by an independent supplier and the manufacturer original defines the GN prefix as the NPT-thread execution.

Installed between a flexible hose and a fixed component, it compensates hose rotation and torsion to reduce hose damage. It is not suitable for fast or continuous rotation. The body is zinc-plated steel with low-friction seals.

The exact NPT supplier card specifies maximum flow 180 l/min, maximum pressure during rotation 100 bar and a separate maximum pressure 300 bar. Apply the lower pressure limit during rotation.

The local PDF retains the complete original manufacturer spread, including the GN NPT option, hydraulic diagram and base-size tables. Representative manufacturer series product image; visible connection threads may show the standard BSP version.
