I was looking through McMaster for a 3/8" pipe cross, when I came across this cross, part #4464K313.
It's rated to 150 psi, which seems painfully low to me. I'm also not sure if that part is schedule 10 or schedule 40. I'm planning to make something of a QDV hybrid, so I need something that can take at least a 10x mix, and steel is usually a good bet, but the low pressure rating has me worried a bit. Explanation? I can't even find the wall thickness for this part to estimate what it can take...
McMaster pressure rating...
before you even worry about the cross please tell us how your going to get a hybrid QDV to work!
it is rated to 150psi just like all the stee fittings in your store. to get a higher rating your gonna have to pay more. oh course it can hold more but how much no know knows...

are the pipes the orings seal against the same diameter? If so, it won't open as you intend. If not, how are you making them different.
you could also try an air spring instead of the coill one.

Please discuss the design here: http://www.spudfiles.com/forums/viewtop ... tml#292692
The title and location are more appropriate.

Looks like the left hand side of the piston is within a section of pipe inside the fitting which could give the area difference to blow back the piston.
I feel sorry for that front o-ring, it's gonna get toasted
