Example of a 3D model generated using this template
(model #1016)

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.

Keywords: O-ring, toroidal seal, round seal, annular seal, circular gasket, O-shaped gasket, elastic ring seal, compression ring, toroid gasket, standard O-ring

Parameters

	name	unit	label
#1	inner diameter (ID)	mm	ID
#2	cross section (CS)	mm	CS

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

Model search and on-demand generation

On-demand generation is available for this template. If the model does not exist, on-demand generation will be offered. Feasibility will be assessed on the on-demand generation page.

This form allows you to find existing models based on the parameters of your choice. Some parameters may intentionally not be available for search.

You can leave fields empty; they will be ignored. Also, if the results do not meet your expectations, try another search and leave one or more less important parameter(s) empty.

The results are displayed from the most relevant to the least relevant.

A star indicates that the model exactly matches your search criteria or is very close.
