just bought these and assembled it but never used, decided to go in a simpler direction. i don't know if anyone can use this but i will just wind up throwing these in a box and forgetting about them so maybe someone will want them. i am not going through the hassle of sellings these seperately so it's all or nothing here. i have off amazon 2 each of the nipples, tee's and valves. why two tee's? because i screwed up the order new was $35 plus shipping i will sell for $20 flat and include the shipping. if you are local to chicago and want to pick them up, then $15. thanx for looking.
