Abstract
A tubular joint has a pair of tubular members (10, 12) with end hubs (14, 16) in opposed relation and secured by a clamp (22). A primary seal ring (40) has external tapered sealing surfaces (42, 44) engaging internal tapered sealing surfaces (28, 30) on the hubs (14, 16) to provide a primary seal. Secondary sealing surfaces (32, 36) on the hubs (14, 16) are engaged by O-rings (62, 64) as shown in FIG. 4 to seal against external fluid flow to the seal ring (40). O-rings (62, 64) permit internal fluid flow outwardly from the seal ring (40) as shown in FIG. 3.
