i made a 2" coaxail piston valve and have final come across a problem. my bumper.
this was my original plan with the bumper behind the ball valve. the threaded part is so i can have access to the piston if it dosent work but i just realzed that the ID of 2" male threaded adapter is smaller than the ID of 2" pipe
this a picture of the male adaptor inside the female adapter. you can see it is consiterably smaller
the peices inside each other form the side
and my piston
the only thing i can think of it to just have the bumper inbetween the fittings but i cant close it off how would i go about doing this? help would realy...well help
