Got a deal on some Cornies this weekend, but all are of dubious background and without question need the gaskets replaced. I searched around and found them running from $2.50-$4.00 plus shipping for the ball lock kits. I then found this place and got enough for five cornies with extra quick disconnect/dip tube rings for less than 10 bucks delivered. Note the additional discounts for more kits also.Maybe everyone gets them there, but I thought it was pretty thrifty. Just passin it on.
