Got bored this morning... Put a couple pieces of the all stainless Swagelok regulator I've been piecing together, together.
I ran into a little snag I thought I'd share as it's a pretty common problem with an easy solution.
Taped the parts I was going to assemble:
The cga-320 nut went in just fine. (they always go in easy because you don't need it pointing in any specific direction.) When I tightened down the high pressure gauge, I couldn't get it tight and straight. Either I was going to have to really wrench down on it (which is not something you to do with stainless steel as you could break a thread and have to throw the whole thing away) or take it back off, clean off all the tape scraps and re-tape it, using more tape. (sometimes less if you've already got more than 4 turns on the fitting)
That's it for now. I'm waiting on some fittings from Swagelok to get shipped. It's a funny thing about Swagelok - they take FOREVER sometimes to get you parts if they have to make them just for you.
A random note about gauges.
I love these WIKA 232.54 series stainless gauges. The quality/appearance rivals that of Swagelok. Not quite as nice though. They can be had for a lot less money anyway. If you find yourself on ebay looking for gauges for whatever reason, pay real close attention to the model numbers and not just the appearance. A slight 'one number' off difference like 232.54 and 232.53 doesn't just mean they are slightly different. They will be way off. Even if you find a set with the same matching model numbers they could be years apart from when they were produced. So you've still a got a little bit of 'chancing it' happening. Just thought I'd share.
