so i got me a din reg..... now for the tanks

[scubajohn921]

ok so i have my first reg, a cressi ellipse alaska din... now...... when i go to my LDS to rent a tank,i ask for a steel hp 80/100/120 right????? or?? is there special lingo i use?? i went with din as its something i will grow and learn with however when i got certified we didnt even hint on din regs or din anything..... im kinda anxious about using it to be honest any basic pointers from renting a tank at the LDS to general attachment to the tank.... also i will be purchasing my own cylinders eventually so the rental thing wont be for long, I appreciate any pointers

you may need a din to yoke adapter. There is a good chance your lds wont have any rental tanks with din yokes.

At least you aren't as clueless as a couple from Southern Calif that showed up at the Maui dive op I used yesterday. They passed DIN regs to the boat crew to setup, then responded with a blank look when the crew asked if they had din-to-yoke adaptors.

Their LDS had sold them DIN regs, but hadn't mentioned that in many resort areas DIN tanks aren't available.

Their nice, new regs stayed in the gearbag while they used rental regs with the yoke valved tanks.

--------------------

Scubajohn921 -- what counts is what sort of valve the tank has. Just ask for a tank with a DIN valve. Don't forget to adjust your weighting as you change tank types --- there is a lot of difference in the buoyancy of different tanks.

Din valves can be but on most cylinders, but the majority of din valves are on steel cylinders. As long as you make it clear to your LDS that you have a din fitting there should be no problem, but a din to yoke adapter is a must for you save a dive kit. At least until youve aquired enough experience to switch the actual fitting on your fist stage to fit whatever cyinder you come across.

thanks guys, once again i appreciate the knowledge here, the din to yoke was something i included in my package for travel purposes ill be askin for a tank with a din valve when i go in this weekend

There may be other manufacturers too, but PST (Pressed Steel Tanks) uses a valve that converts between yoke and DIN with a simple insert. Of course, now that you have a DIN fitting on your regulator, you won't need the yoke capability on your tank.

Like others have said, don't forget you yoke-to-DIN adaptor when you go on vacation.

Don't forget that DIN is not universal either, there are 2 types. You have 200 and 300 bar DIN setups and they are not compatible. Make sure you specify which one you have.

Don't forget that DIN is not universal either, there are 2 types. You have 200 and 300 bar DIN setups and they are not compatible. Make sure you specify which one you have.

That isn't totally true, they are compatible in one direction only. The 300 bar DIN vavles will be found on HP tanks (Greater than 3450 working pressure) and have 9 threads and fit a 5/8 tank neck, the 200 (232 I think) Bar DIN valves will be installed on LP tanks (even the PST E-8s) have 7 threads and fit 3/4" tank neck (The neck on LP steels and AL tanks).

Regulators come in 300 bar (almost exclusively now) and will fit either valve, with extra threads showing on a LP tank but its no big deal. Whether there are still regulators being sold with 232 bar DIN fittings is a debate we just had at the shop last night, if you find a 232 bar DIN regulator (7 threads) it will not fit the 300 bar HP valves. It doesn't reach deep enough in to seat.

There may be other manufacturers too, but PST (Pressed Steel Tanks) uses a valve that converts between yoke and DIN with a simple insert.

There is a screw-in "donut" that will convert the 232 bar vavle to accept a yoke fitting. This will fit any LP valve. There is no donut available for the deeper HP valves, most yoke regulators are not rated to 3500 psi.

 

[cummings66]

Yes, you're correct and it is a concern that a person should be aware of although I thought it was 5 and 7 threads for them. All I know for sure is that mine is a 300 bar DIN and my tanks are 3500 PSI and configured for them.

I have the adaptors just in case I want to rent something with a yoke mount.

....I thought it was 5 and 7 threads for them.

I think you're right on that, I mis-stated
