This template generates toroidal seals (commonly known as O-rings in English). These seals are shaped like a "doughnut", or more precisely, like a torus—hence the name "toroidal seal".
O-rings are defined by two key dimensions: the inner diameter (ID) and the circular cross-section (or thickness), referred to as CS.
O-rings are used to ensure sealing in various mechanical and hydraulic systems, such as fittings, cylinders, or pumps.
This template was the very first to offer on-demand generation on iteration3d.fr.
Keywords: O-ring, toroidal seal, round seal, annular seal, circular gasket, O-shaped gasket, elastic ring seal, compression ring, toroid gasket, standard O-ring

Additional information
To determine the outer diameter (OD), apply the formula OD = ID + 2×CS.
