Abstract: The present invention relates to a conduit drain for removing liquid condensation in a vertical conduit. Moisture flows down the interior walls of the conduit and collects in a collection lip in the conduit drain. A drain channel is produced around the inner circumference of the conduit drain by the collection lip. The moisture collects within the drain channel and is drawn off into a drain port that is coupled to a drain pipe.

Abstract: A system and method is taught of positively joining to pipes, such as stovepipe or conduit. A first pipe is made with an indentation about the perimeter of one end, into which a second pipe is fitted snugly. The second pipe has a plurality of protrusions about the perimeter near the end to be inserted into the first pipe. The protrusions are shaped so as to allow passage past the indentation in the first pipe during insertion of the second pipe, while resisting disassembly by withdrawing the second pipe.

Abstract: A pipe connection includes a first having a male end and a second pipe having a female end and a gasket. The female end has a recess area sized to accept the gasket. The gasket has at least one flexible protrusion extending radially towards the center of the pipe forming a diameter that is less than the diameter of the male end which frictionally engages the male end of the second pipe. Optionally, the female end may include rigid dimples that exert pressure onto the male end to prevent the two pipes from separating. The pipe connection may be used in conjunction with a clamp.

Abstract: A connector system for coupling first and second venting devices, at least one of which comprises a flexible vent pipe, includes a venting device connector having first and second ends. A first end of the venting device connector includes an inner vent member having an outside diameter smaller than the inside diameter of the flexible pipe to which it is to be coupled. An outer flexible vent pipe restraining member circumferentially surrounds an end portion of the inner vent member and has an inside diameter substantially larger than the inner vent member, and generally larger than the outside diameter of a grooved exterior region of the flexible vent pipe to which the connector is to be coupled. A circumference reducer allows the first end of the venting device connector to be securely and releasably attached to the flexible vent pipe.
