Ive got a pair of HKS sequential BOVS (second hand) and up untill an hour ago I had every part for them, Hohever I needed to replace the very small pipes on them so I went to my local very small pipe shop and he sold me a piece of pipe for me to cut and fit, got back home and started fitting the pipes when I realised that one of the little connectors (the disk shaped one that you attach the small pipe to either side of) has gone missing, either Ive left it in the shop or the dog has ate it, how important is this part? I thought it may be just a connector but when I looked at the other one it isnt just a straight through pipe so im assuming there is something important in the disk, soooooo can I get away with just fitting pipe to pipe without the disk thing or will I have to get another, and if so from where??

if im not mistaken i believe its a non return valve.how they will work with this left off im not sure.

I thought it might be a non return as well, but I tried the one I still have and you can blow down it either way with no resistance whatsoever but you cant see through it so theirs def something in it
