Abstract
A first and second conduit are connected together by a screw thread attachment. A gasket hermetically seals the first and second conduit together. The first conduit has a seal member which is shaped to engage a sealing surface of the first conduit. Spring washers force the seal member against the sealing surface. The seal member has an extension which engages the gasket such that when the conduits are screwed togther, the seal member is lifted off of the sealing surface.
