About Spring Energised C-Rings


· Wide range of standard free heights from 1.58 mm to 12.7 mm
· Internal pressure - Diameters range from 19.05 mm to 3000 mm
· External pressure - Diameters range from 16.51 mm to 3000 mm
· Circular, race-track or other custom shapes available


· Similiar to C-Rings but higher loads for use with rougher mating surfaces
· For internally pressurised joints & for externally pressurised joints to avoid          passage of working fluid into the sealing cavity
· Best choice for non-flat mating surfaces
· For pressure vessel closures; steam generators, gasoline/diesel engine fire        rings, exhaust joints, flanges with a rougher surface finish
