ABSTRACT:
A metal face sealing coupler providing high elasticity and/or spring back to maintain effective annular sealing between male and female coupling members while allowing and lateral movement for make up of the two coupling members. The female member has a main body with an internal poppet valve and a metal face seal with high deflection and spring back capability, generally an E-ring. An outer shell is attached to the main body and provides lateral support for the metal sealing element, lateral guidance and vertical connection to a support ring and lateral guidance and indexing of the female member during make up with the male member. The support ring allows the main body a limited lateral movement when the female member makes up with the male member. The female member fits inside the outer shell. The male member, with an internal poppet valve, engages the metal face sealing element, which flexes and allows for sealing in any position within a pre defined longitudinal tolerance envelope. The metal sealing element is plastically and elastically deformed to the proper relative position between the male and female members and has a revocable significant elastic spring back when the male and female members are parted which allows the connection to be made up repeatedly with the same seal.
