Abstract
A coupling ideally suited for sealing between components such as a fluoropolymer valve body (50) and a fluoropolymer manifold (52) or for coupling tubing end portions, utilizes structure on said components for defining the sealing surfaces. In a preferred embodiment, the coupling comprises a male protruding portion (62), a recessed female receiving portion (64), and a clamping means. The clamping means (92) has an inner threaded surface for engaging a correspondingly threaded portion of the male protruding portion. The male protruding portion is shaped, generally, as a converging rounded conical frustum (65.1) having an exterior surface, a primary sealing surface, a first stop surface (78), a second cooperating stop surface, and a fluid flow duct. The fluid flow duct is preferably concentrically positioned. The recessed portion has a circular perimeter, an inwardly projecting annular ring (74), a first cooperating stop surface, a second stop (82) surface, and a fluid flow duct. The male protruding portion forms a seal by confronting the primary sealing surface and the annular sealing ring.
