Oleodinamica Marchesini GX1090 GGL 1 INOX in-line rotating coupling

Oleodinamica Marchesini GX1090 is the GGL 1 INOX stainless-steel rotating coupling with 1" BSP connections. This exact full GX code is selected on the named-brand supplier offer. The manufacturer documents GX in place of G for the stainless body option; the matching printed base row is G1090. This is an observed commercial article, not a generated ordering-code combination.

The in-line coupling connects a flexible hose to a fixed component to compensate rotation and torsion. The manufacturer states that the family is unsuitable for fast, continuous rotation. Connect the P ports in the arrangement shown on the original drawing.

The standard steel G1090 row lists maximum flow 180 l/min, pressure during rotation 100 bar and general maximum pressure 300 bar. These remain explicitly labelled base-execution references. The shared sheet does not give a separate GX1090 stainless rating or mass row, so no unqualified pressure, flow or mass filter is assigned to this GX profile.

The body is identified as stainless steel without a specific AISI grade. Low-friction seals are described without a compound specification. The original common-family drawing supports the connection arrangement, while exact stainless execution limits and dimensions require confirmation for the intended duty.

The local technical PDF retains the complete relevant original factory spread, including the applicable row, spring table or material-code convention, hydraulic symbol and drawing. Neighbouring executions apply only to their identified rows. Oil temperature 50 °C and viscosity 30 cSt beside curves are reference test conditions rather than operating limits.
