Abstract: A pipe and snap connector assembly including mating male and female pipes joined by a clam-shell type connector. The female pipe receives a portion of the male pipe, and each pipe provides a radial flange configured such that there is a gap between the radial flanges when the male pipe is received in the female pipe. A sealing washer or seal is disposed between the flanges, in the gap. The clam-shell type connector is of open-ended barrel construction, and includes a radial clamp cavity that is sized to contact the radial flanges on the male and female pipes and axially compress them against the seal to provide a fluid-tight connection of the pipes. A latch and catch mechanism on the connector can be opened and closed without the use of special tools.

Abstract: A power element assembly is disclosed for use in a liquid environment to operate devices such as valves, switches and the like wherein such assembly is provided with an elastomeric diaphragm having an integral sealing neck with internal seal beads that are sealingly retained in engagement with a piston by prescribed compression of the sealing neck at assembly.
