Hi Guys,

What sort of pressures have people had aluminium or stainless camlocks up to without failure? Particularly the larger sizes 2" and up.

Cheers

For a combustion/hybrid usage and 2" camlocks, I wouldn't think twice about using the plastic ones with up to a 2x mix or roughly 200 psi, and 350psi (3 - 4 x) or so with the stainless connectors.

I would be somewhat more conservative on a pneumatic design, 150 psi on the poly and 250 psi on the stainless.

Derate the 3" ones a little more as well.

They're rated to 250 psi on McMaster and could probably stand a fair bit more.

If you're using it as a burst disk holder I wouldn't be too afraid of a failure as you'll have a fair amount of trouble finding a disk that will burst above 250 psi in such a large size.

daberno- aluminum pop can layers can easily hold that in a cam-lock

I wouldn't trust cam-locks on a hybrid past 4x ever, but for any combustion cannons you should be fine.

Really? Even in a 2" or 3" one? If so, that's good to know since I have a 3" set I'm going to put to use.
