ABSTRACT:
An annular seal is placed between the flanges of two pipes or conduits to seal against high pressure or vacuum. A flat inner ring has the inside diameter of the pipe and is formed on its outer edge with a truncated V groove. A flat outer ring has an inside diameter slightly greater than the outside diameter of the inner ring and its inner edge is also formed with a truncated V groove. A circular cross-section O ring is received in the two grooves, its unstressed diameter being greater than the thickness of the flat rings so that when the seal is placed between two flanges the O ring flexes to partially fill the grooves and to seal against both flanges. To locate the annular seal accurately a thin locating ring surrounds the annular seal and is detachably secured thereto by lugs which fit into a groove in the external edge of the outer flat ring. The locating ring has a pair of opposed ears which are slotted or otherwise apertured to receive the bolts which draw the pipe flanges together. Since the flanges and bolt hole circles may be of varying diameters depending upon the designed pressure for pipes of the same nominal inside diameter, the slots or apertures are shaped to center the seal for several different size flanges.
