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.
