The higher end gauges (check WIKA and Ashcroft, for example) have variations of each model that are dry or liquid-filled. For us, the only reason to go liquid-filled is if we find them at a good price. Other than that, it's an aesthetics thing.
What solenoid is that round silver one? Is it NPT sized threads like the burkert?
Aquariumplants.com is out of stock on burkert solenoids and I need an alternative place to get one.
That a numatic solenoid, I wanted one so bad. I think it's 10/32 like the Clippard. Bettail changes the manifold to 1/8 NPT, I'm sure it works fine. BUT, there is another solenoid that already has 1/8 NPT and is the same size.
Bettail, what happen to that japanese regulator you were making?
