The only ones I have seen in SS are JIC flare.
SS-2404-06-06 - 3/8" JIC 37° x 3/8" Male Pipe - Stainless from the site listed above
They are pretty readily available, but if you have SAE hoses then you might be out of luck and stuck with lead free brass. I am sure someone makes them, but might not be cheap.
NPT Flare? If its Male NPT you could do something like:
SS-1405-06-06 - 3/8" Female Pipe x 3/8" Female Pipe Swivel - Stainless
SS-2404-06-06 - 3/8" JIC 37° x 3/8" Male Pipe - Stainless
I think he meant SAE flare, most of the filter driers are 45 flares and it is hard to find SS fittings in 45.
It's probably pricey but these guys can do custom fittings

might be nice for those hard/impossible to find fittings.
Anyone ever order from hydraulics direct? The prices are a lot cheaper than anywhere else..

I'm trying to find out if they are cheap, and have nasty threads or anything.. They say that they sell Parker. But I feel like a lot of these fittings would not be that cheap if it were Parker.
Just wanted to update this thread
The ball valves I ended up getting from stainlessstealfittings.com were Sharpe ball valves and mine came leaky. The seem to seal OK until solvent is actually flowing then I can hear them leaking a tiny bit. If I wiggle the handle a bit I can get the sound to stop but I am not convinced they are fully sealed.
I am trying to get set up in a new spot and don't have an air compressor yet so I can't investigate fully. After 4 runs in the machine I only lost 2 lbs of solvent without adding any so the leak can't be huge but any leak is unacceptable. Probably should have just spent the money for parker or swagelock :/
Do they have a packing gland nut that you can tighten?
