Oleodinamica Marchesini GX1050 GGL 1/4 INOX in-line rotating coupling

Oleodinamica Marchesini GX1050 is the in-line stainless-steel rotating coupling with 1/4" BSP connections. The manufacturer explicitly identifies this complete GX code as the stainless version of G1050, and the exact named-brand supplier offer selects the same code. No NPT code or other size is generated.

The coupling connects a flexible hose to a fixed component to compensate hose rotation and torsion. The manufacturer states that this family is unsuitable for fast, continuous rotation. Connect the P ports according to the original in-line arrangement and allow for the actual installation envelope.

The table on the shared sheet lists the standard G1050 steel execution at 25 l/min maximum flow, 200 bar maximum pressure during rotation and 400 bar general maximum pressure. These are retained only as explicitly labelled base-execution references. The page identifies the GX stainless option but does not give a separate GX rating or mass row; no unqualified pressure, flow or mass filter is assigned to this GX profile.

The stainless grade and seal compound are not specified by the exact factory option example. The low-friction seal description and the original family drawing are retained without assuming a particular AISI grade or a continuous-rotation duty. Confirm exact GX pressure and flow limits for the intended application.

The local technical PDF retains the complete relevant original manufacturer spread, including the exact spring-code matrix, cartridge row or stainless-code example. Neighbouring executions apply only to their identified rows. Any 50 °C oil temperature and 30 cSt viscosity beside curves are reference conditions rather than operating limits.
