Golem Gear is proud to present a Total Solution by Omniswivel.

Hi Jakub,

Looks great. Been at M&J webpage and golems as well. As I am starting from scratch this is very much worth considering.

But, I cannot find any specs on the flowrates. CEJN221 specifies min 500l/min at a pressuredrop of 0.5bar over a coupling, meassured at 6bar.
Also they specify a relative bore of 5mm.

Any chance you have similar information on the Omniswivel parts?

Regards
Nicolai

I do not know the flow rates, etc.. will try to find out.
The bore is 5mm as well.

I'd also prefer that there was just one standard set of QDs (I also wish that there was just one set of measurement units

) , but if that can't be done this is the next best solution. We also carry Hose repair kits that let you build any length hose with 3/8 and 9/16 threads, add ODs and you are set.

Rather than send some parts back to the other side of the world that werent compatible with my other cejn stuff thought I would have a play on the lathe so this is what works.The omni female coupling will fit all cejn nipples.The omni nipple on the check valve needs the nose shaped more like a bull nose and .5mm removed from the indent of the nipple so the cejn female couplings will fit.Thought this might help some one else out.

Since your supplier is the only one using the non-CEJN standard, why don't you, as a large volume vendor, point this out to them and ask them for a production change? All it would take is purchase of a different part number QD as an OEM part for the hose end, and a tiny change to the CNC code for the parts they produce in house. Seems that they can take either of two courses: Making a change to bring their product into line with the standard, or continuing to be non-standard, which will drive at least a portion of the prospective purchasers elsewhere. There's no downside to 'Plan A" and a huge downside to "Plan B". Seems a no-brainer to me.

Just an idea...... which does not at all take anything away from a "well done" in getting the male nipple to 3/8-24 stubs made.

Dave,

I already did. So far no change. I guess it is their business decission, it might have to do with patents, copyrights, etc..

I'll bring it up again, and again

Thanks,
Jakub

Assuming that the above comments are correct, the only change omniswivel would need to make would be to the male fittings?
If they did that then cejn female fittings would fit omniswivel male fittings, and omniswivel female fittings already fit cejn male fittings. If they did it this way, then all new parts would be backwards compatible with the old omniswivel fittings.

Jakub,
I understand the need for a check valve male QD on the gas block but why did you put one on the BOV ??

I think the illustration is just to show options a diver can do... Not that it is required.

one other suggestion would be to make the female coupling with and without the locking ring .I am sure there are applications where it is needed but in cold water heavy gloves it requires both hands and a visual check to undo for a gas switch.Nothing five minutes with a dremel cant fix to cut the tab off but might be nice to have the option when purchasing.

Actually the QDs were still in flux. Now they all have a locking ring but with 90 degree rotation stop, so even with gloves you rotate to the stop, pull on it and if it does not disconnect rotate to the other stop and pull to disconnect.

I'll see if we can bring back the no stop ones as well if there is enough
interest.

On a good note, I spoke to Joe from Omniswivel today and they will consider making the QDs compatible.

I need a sample of male and female CEJN QD, to make it happen. Can anybody provide them to me?

Thanks,

I agree

I run my BOV off my deep bailout, and some dives require us to take our stages off before climbing up the ladder. Not easy with that infernal locking tab, brilliant idea though it is.

Hadn't thought of cutting it off - cheers kiwidiver

Also, does anyone know if you can get a standard apeks LP inflator male (BC inflator nipple) to fit the BOV?

Cheers
