Title: High pressure valve for chromatography

Abstract: A valve in which a cold flowable, non-absorbing sealing member, such as tetrafluoroethylene resin, is confined within complementary surfaces of an outer hollow body and an inner, rotatable element, and substantial pressure is imposed on the member to compress and cold flow its material into sealing engagement with the complementary surfaces. At least one passage is formed in the inner element, and ports are formed in the surrounding member and body so as to come into selective alinement with the passage.
