Abstract:
1. A rain tight fitting for connecting tubing to a panel comprising: a tubular body member including a forward end, a rearward end having an inner periphery, and external threads on said rearward end; a compression nut internally threaded to engage said external threads on said rearward end of said tubular body member; a seal ring seat on said inner periphery of said rearward end; a seal ring disposed against said seal ring seat, said seal ring a continuous ring having an inner periphery, an outer periphery, and a trailing edge, said seal ring formed of plastic having a Rockwell R Hardness between 110 and 120; said tubing includes an outer periphery; said inner periphery of said seal ring is greater than said outer periphery of said tubing; a compression ring disposed against said first seal ring, said compression ring a split ring having a leading edge; and said leading edge of said compression ring engaging said trailing edge of said seal ring; wherein tightening of said compression nut upon said rearward end of said tubular body member causes said inner periphery of said seal ring to collapse in diameter until said inner periphery of said seal ring is in firm contact with said outer periphery of said tubing thereby holding said tubing firmly within said fitting.
