Abstract
The present invention provides a seal for use in a modular flow device and is utilized for joining and aligning a first mating surface and second mating surface having axial flow passageways. The seal comprises a protruding annular radiused edge about the axial passageway of the first mating surface and an annular groove about the axial passageway of the second mating surface. The groove has an inner angled wall for engaging with the annular radiused edge when the mating surfaces are compressively joined. Thus, a leak proof seal is formed around the fluid passageway and the passageways are aligned with respect to each other. The invention also relates to check valves for use with modular surface mount systems in which the check valve can be used as a surface mounted component or as part of a substrate that is mounted to or between other substrates and components.
