The roughly cylindrical seal comprises four sealing surfaces, two sealing = formed by the longitudinal edge, and two surfaces circular sealing surfaces — IM 31 Igo 1-1 I ii- 32 IN till I • i III 44 ' formed by either side of a bulge located halfway along the outer diameter. 10 These surfaces correspond with sealing surfaces on the pieces of equipment to be joined. These pieces of equipment also utilize testing ports in fluid com- munication with the seal in order to ensure a secure connection. ii- © 34A in N • - al \ -\ I 42 IN ,-, FIG. 3A © B ei C
