ResOne 8pk Oxygen Tubing Connector Kit (2ea Straight, Swivel, Y, Christmas Tree) #TC-190-1

I'm sorry to say that I had to make a purchase of a couple of these just for the swivel connectors inside the package. I tried to make several different purchases for just the swivels and didn't have any luck, not even to order any ahead of time but buying the kits were the only way I could get them. They show many different pictures of them offering them from 1 at a time through a package of 100 but couldn't place the order any other way except to but a variety kit they were included in also. The kit doesn't cost very much but the other pieces are just a waste to me. Maybe some day they will be able to fill the orders without having to purchase the kits. Other than that I'm happy with the purchase. Will do it again if I have to.
