    Abstract: The present invention relates to exhaust condensate removal equipment for energy efficient heating apparatuses that may be positioned either vertically or any angle off horizontal. The device collects condensate from ducts and may be retrofit into existing systems. The device has an inner chamber that collects and directs condensates toward a drain nipple through which the condensate is then removed from the sealed system. The system may optionally include a reusable seal and clamp for ease of maintenance or retrofitting an existing system.

  • Coupling with built-in gasket and mechanical locking device
    Patent number: 6026803
    Abstract: The present invention discloses a coupling for use in vent systems which is self-sealing. The coupling includes a gasket in a female part of the coupling that seals against an end of a male part. The female part also including a mechanical locking device that clamps onto a recess in the male part to prevent disconnection. The coupling prevents puddling of corrosive fluids in the coupling at points of metal-to-metal contact and, hence, prevents premature corrosion.
