tapped stainless pipe to mount individual solenoids

I wouldn't trust it. Plus it has garden hose threads. I'm not 100% sold yet on the SS manifold until I see how it's made!
 
I also found a Dema SS solenoid manifold like the Kip brass ones. But from looking at the pictures, it
appears it has brass bodied solenoids. It is $237.
 
I do work for a guy who uses the Dema block solenoids. They're a pain in the ass. They get stuck open for no apparent reason, and when you open them to clear debris that's never there the seat falls out (along with the two o-rings) if you aren't hyper careful. If pressure gets trapped, you can't just loosen the stem and relieve the pressure or the o-ring comes out of the seat and gets pinched and cut when you tighten it down. Also when there's a pressure issue and the solenoids can't open, the coils get so hot they melt themselves to the stem.

Otherwise, they're great.
 
I use regular blue Loctite for sealant. If you tighten it really tight, you'll have trouble getting them apart. I tape the fittings that go into the solenoids and regulators, or anything that might eventually get replaced.

The John Guest push tubing fittings are the best I've used, but even they will eventually leak. I'm using a compression fitting that doesn't need an inner support.

Here's a bank I replaced for someone:
