ABSTRACT:
A resilient seal ring for a tubular connection having an outside periphery that comes to a peak. The peak includes preferably two chamfered sides at respective angles to the axis of the ring that are greater than the adjacent conical surface angle. The crown of the peaked top is preferably flat. The connection includes a rectangular groove in a shallowly tapered conical surface of the pin member, preferably on a forward metal-to-metal sealing surface. The groove is slightly less deep than the seal ring.
