Abstract
A sealing unit includes a mismatched metal-to-metal seal and an o-ring seal with a vent hole therebetween. The mismatched metal-to-metal seal may provide a sealing surface between two metals that may withstand high temperatures and pressure while avoiding leakage over many cycles. The sealing units of the present invention may provide a seal capable of withstanding pressures greater than about 5,000 psig, and typically greater than 6,000 psig, and more typically greater than 7,000 psig; and temperatures greater than about 300° F., and typically greater than about 400° F., and more typically greater than about 500° F. over a service life of more than 5,000 cycles. By providing a vent hole between the metal-to-metal seal and the o-ring seal, should either seal leak, damage to the other/good seal may be prevented by expelling the leak out of the system.
