I have used that tool many times back at Divers Service Center in the 70's. I also have some new modified/ improved version and they are very handy to place the regulator and remove the first stage and all the other components, with one exception. That tool actually gets in the way of putting a good wrench on the hookah port. If you look the hookah port fits in that slot and there is no good way to put a wrench on it. Even if you can put a wrench on it, you are not grabbing the body to avoid rotation in the axis that you need to remove the hookah port. I have other custom specialized tools and there are many ways to accomplish some tasks, but based on my experience, the method I describe is one of the few I am comfortable using while dissembling a stubborn hookah port, where long cheater pipe is needed. This method is after disassembling all the other parts. Being there done that... If something is not very clear, please let me know and I will try to explain it better. Had to edit a typo.

Oh yes thank you for the reminder, John. I remember seeing the wooden one and I believe it was actually posted by Bill here I tried with it mounted on tank, but it didn’t budge with reasonable torque. Do you think in this case for the amount of force that will likely be required, I’m better off limiting the components involved and trying Luis’ method? At this point I would do as Luis suggested and take the whole thing apart and use wooden blocks to hold the body in a vise. It's good to do that and give it a good cleanup that it may need anyway. If you are reluctant to do that you might try the old timer heat trick, but you will have to be careful not to overheat to point of melting plastics and rubber parts or damage the chrome. A small propane torch can be used to apply enough heat evenly around just the cap that it just becomes too hot to hold... no more. Then apply the wrench. Actually I like the complete disassembly method better!
If needed you can combine what I described with a little heat like Bill is describing. What I am describing involves removing everything before trying to tackle the hookah port (again). Therefore, there are no non-metal parts left that can be harmed. You can still harm the chrome, but not if you are careful. Heck, if you really want to loosen it up easily, place the striped down body (all other components removed) with the stuck hookah port in the freezer for a while (or over night) and then all you need is to apply some heat just to the cap. The thermal expansion differential will likely loosen up the cap were you will not need the cheater pipe. Again, limit the heat like Bill described. I like my cheater pipes... I have several custom, for different wrenches... I call it brute force gently applied... You can actually get very good control and allows you to apply a very gradual increasing torque.
YMMV

Great clarification, Luis.

For all of the veteran double hose divers on here, do you have any good solutions for attaching a splitter to the hookah port so that two lp hoses may be attached? I found one of the barbed fittings that would require you to cut the fitting off of a hose as described above, but that still only allows you to attach one hose at a time. Since nobody that I can find online is currently selling the simple 9/16 to 3/8 adapters, are there any other ways to do this? I have tried searching places like MSC supply and McMaster Carr, but I still can't seem to find the right combination of adaptors to make it work. I appreciate any input from guys that have managed to do this without one of those adapters. Or if anyone has one of those adaptors for sale, please let me know. Thanks for your help.

If you're looking for 2 ports for a BC inflator and safe second, I use Sherwood Shadow+ combination units on all my double hose regs. With these I only need one hose and one port.

You are talking about these kinds of splitters: IMG_1824 by John Ratliff, on Flickr IMG_1484 by John Ratliff, on Flickr IMG_1448 by John Ratliff, on Flickr IMG_0014 by John Ratliff, on Flickr I have gotten most of mine off E-Bay, looking at regulators with the splitters. You might look at this one: www.ebay.com/itm/284448348882?hash=item423a715ad2:g:-~0AAOSwGH9gC3ZcJohn

John,
I actually have one of those splitters that I did indeed get from ebay. But the problem is it has that 3/8 male end that won't connect to the hookah without one of those little adapters that nobody is currently making. that is the problem I have been trying to solve.

Vance ( or anyone who would know):
I have read that the threads on the Hookah port are he same as the threads on an O2 fitting. What exactly is the designation (fine or coarse thread, etc ) on both the Hookah (O2?) and LPH 7/8 inch fittings. Both ends of the conversion fitting would have to be female. I would like to search for a conversion fitting with fitting suppliers.

Or a solution might be, to use a standard O2 fitting on one end of the BCD low pressure hose, and the Quick connector fitting, (to attach to the BCD), on the other end of the hose. It would be as simple as removing the 7/8 inch fitting, on one end of the LPH, and installing the O2 fitting, with a fastener that would securely withstand the hose pressure. I used to carry spare fittings required, when I worked in commercial diving, in my tool kit, so was used to working with different fittings at the time. This all assumes that the Hookah port is indeed an O2 fitting. Something like this: www.amronintl.com/catalogsearch/result/?cat=0&q=AHB-40202

The hookah port is 9/16" x 18 tpi. "B" size oxygen fitting threads are the same.

Is Herman out of them? He had some a while back.

adaptors by lwpjr, on Flickr This is what I am going to try once I get my regulator put back together.
