The centering ring assemblies, containing O-rings and positioned between two ISO flanges with matching outer diameters, are crucial for connecting any pair of ISO flanges using quick clamps. These assemblies are extensively utilized in constructing foreline vacuum plumbing and process systems. Both ISO-F and ISO-K flanges utilize these Centering Rings, which incorporate a metal support ring with an elastomer seal, and some also feature an additional metal Outer Ring. These rings are alternatively referred to as ISO centering rings with outer rings or outer centering rings with inner support rings.
