Oleodinamica Marchesini GN1020 GG 90° 1/2 NPT 90-degree rotating coupling

Oleodinamica Marchesini GN1020 is a 90-degree rotating coupling in the GG 90° series, with 1/2" 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 60 l/min, maximum pressure during rotation 150 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.

The supplier heading and selected article identify GN1020 with NPT connections. One copied sentence retains the BSP base code G1020. The explicit NPT article heading, connections and original GN option identify this profile; BSP mass and dimensions are not assigned.
