Tying back an SPG on a stage reg.

[Jimmer]

Ok, maybe I'm an idiot, but I can't seem to come up with a decent way to tie back the SPG on the 6" hose to my first stage, that doesn't come loose, or sloppy or just plain let go. Anyone have any pictures or directions on how to tie it back and what knot to use?

Thanks,

Jim

I'm amazed that this is six inches. Seems so much shorter.

I guess routing depends on your 1st stage. What are you using?

In any case, I hope this helps. It rides on the bottle in the orientation shown in the first picture. The second should give you an idea how to secure it. My suggestion is: put the gage where you want it and make your loop to fit rather than starting with a loop and trying to rig it in place.

6" is the length that I run. I just have the HP port pointing down, fold the SPG back up, and cave line tying the hose together at the base of the HP hose and the base of the SPG so it holds the "U" shape. Here's a link:

Doesn't really show where the line is tied but you get an idea of the shape of the hose and the routing so just find a suitable tie point and you will be good to go. Hope this helps!

Me too, but I had to pull out a ruler to convince myself

I'm using Zeagle DSV's for stage/deco, so they route pretty much identically to the Apeks DS4. Is that bungee cord you use on your Mk25? If so do you leave it on all the time or just loop it up when you are ready to use it?

I had been using some surgical tubing and a 12" hose wrapped around the tank neck. I tried the 6" hoses but ended up having them fail a couple of times a year because of the tight bend.

Now I use this:

and haven't had any problems. It's big enough that you can tell roughly how much gas you have underwater, and is actually pretty easy to read on the surface. It's about the diameter of a quarter.

Yep, it's the same as the cord I have on my necklaced second stage. 3/16", I think. I leave it like that unless I'm servicing my gear.

While it is possible to remove (though maybe not exactly 'easy' as the loop isn't big enough to pull over the gage cylinder without some effort), it's hardly under any load so I can't imagine it's harming the life of the cord.

That said, Peter Steinhoff (from the link battles posted) is a do-it-yourselfer-extraordinaire, and his advise is sound. For one thing, cave line is certainly easier to tie.

HD zip tie.

Jim,

Several have given great suggestions, I've added a cpl pictures of what they look like using inner tube. In the end I was not pleased as they seemed to move once the pressure was turned on. I eventually decided to use zip ties, and then when breaking the gear down cut them with nippers. Some say they leave them tied like that all the time, however it only takes a few extra seconds to zippem up so I figured I would save the stress on the hoses and not store them bent.

Safe diving,

Kenny
