Re: [PSUBS-MAILIST] Valve Advice
I to like Swagelok 1/4 inch high pressure ball valves. Make sure you check the pressure rating if you get these off eBay as there are two different ratings. For HP scuba tanks, you need the higher rating version. Also get the SS version.
I have used these for over 25 years with great success.
