    Fresh water in one first stage, salt water in another

    On the pony reg, I would remove the SPG hose and plug the port (to keep from pushing water up the hose and into the SPG itself), and put it on a tank and purge both seconds extensively. The dry air from the tank will flush out/dry out any fresh water that got into it.... and the sooner the...

    Tank thread/fitting/valve question

    Well, that is one of the Sportsways "1/2" inch valves. I don't have one pulled right now to be able to compare measurements (The specs I mentioned above were quoted from others... I apologize). Bright side, it's an easy valve to rebuild and should be fine. Downside is if you want din, looks...

    Tank thread/fitting/valve question

    I, for one, didn't see anything rude. And I'm sorry for the loss (both the replaceable stuff and the irreplaceable cats). Best, James

    Tank thread/fitting/valve question

    Your oddball thread is probably a 1/2 NPS (straight) thread. Sportsways and one or two others made them. I have one tank with a Sportsways 1/2 NPS... you can occasionally find valves on ebay, or check if The Scuba Museum has any (his stock varies). Or, you can have a modern valve machined...

    Hookah Port question

    That's the fitting for a second stage, different inside from the O2 b fitting that the hookah port uses. If you only need one hose, you can do O2 B fitting with a barb, cut the 1st stage end off an LP hose and have it crimped onto the B fitting...

    Recreational Pony Bottles, completely unnecessary? Why or why not?

    This statement here, reads as that you didn't want to debate.... you wanted to hash out a disagreement with specific people. I think that would have been better handled in a private conversation. But, since you did invite conversation from all.... could you respond specifically to why you see...

    Recreational Pony Bottles, completely unnecessary? Why or why not?

    I'm trying to discuss in good faith, but I can't ignore moving goalposts. The OP presented the risk of wrong mix in a pony tank. On further discussion he says he teaches all students to analyze every tank, and some agencies teach on EAN to start (so now we are making Nitrox the minimum entry...

    Recreational Pony Bottles, completely unnecessary? Why or why not?

    So I need to borrow an analyzer I'm not trained on to test tanks from a shop that only has air? Or if a new diver goes to a shop that also handles mixed gasses, they should borrow an analyzer, that I repeat; THEY HAVE NO TRAINING FOR (academic or practical), and test it themselves? I fail to...

    Recreational Pony Bottles, completely unnecessary? Why or why not?

    So you recommend all divers (including newly minted OW) at all shops use an O2 analyzer (that they likely aren't trained on) to test every tank they rent? If we are going down the example of that rabbit hole (if a shop will fill a pony with something other than requested, then the mix in any...

    Recreational Pony Bottles, completely unnecessary? Why or why not?

    Yes I did... and it seems people still want to see it that way. I have yet to see an answer on why having a pony means you cannot have done proper gas planning (or adhere to it). Are pony bottles necessary on rec dives... no. However they are a hell of a benefit on some. An example I do...

    Recreational Pony Bottles, completely unnecessary? Why or why not?

    Respectfully, why is it one or the other. People are acting like carrying a pony is mutually exclusive to using proper planning. James

    Regulator Service Tech Training - Tool Splitoff

    Legally, a tool is a tool.... only time patents come into play (if it's a patented tool) is if you are trying to sell it. I make parts with my printer often, and tools on occasion.... an example is the D420 face spanner that SP sells for some ridiculous amount. Way cheaper to print a tool for...

    Hookah Port question

    With that one, you would need a 1/4 NPT male to 3/8-24 adapter. The one AD has is Oxygen B to Oxygen B, and then half of this: DGX Adapter: Turns LP Reg Hose into BC Inflator Hose (it separates into 2 pieces, a 9/16 male to 3/18-24 female adapter and a 3/8 male to LP quick disconnect). Here's a...

    Hookah Port question

    The air passages in the splitter are right at the edge of the bore.... An o ring or washer would block them, so I seal it with tape on the threads.

    Hookah Port question

    It's a 9/16 oxygen fitting, oddly enough. @herman has made adapters in the past, don't know if he still does. On a few of mine I'm using this: DGX LP Y-Block: 2 Port 3/8-Inch F = 1 Port 9/16-Inch F With lots of teflon tape It's still finicky to seal, but works. Respectfully, James
