Zeagle Zrd looks like a crossbred Apeks

[rescuediver009]

A little better way to state it would be "there are many similarities in the current Zeagle made parts kits and the Apeks made kits, except for the HP seat."
But as Scott stated, and you well know, "They are a different set of parts!!!"
(In reality only the 0011 and 0012 port plug o-rings could be interchanged.)

IF you are going to say that the o-rings for the port plugs are the same you must be comparing their size. Tear into a kit of a Zeagle and Apeks compare the sizes and you will find that there are alot more similarities. This applies to the second stage moreso. I never mentioned that they were the same set or interchangeable parts. Thanks for the grammar lesson though...

As service techs we have a tendancy to compare similarities in regulators. In looking more closely at the rest of the first stage many more differences are apparent. Removable conical HP valve, inverted and conical filters on yoke models too, and polymer diaphragm clamp rings and DIN wheels are the most noticeable.

I can appreciate you wanting to distinguish Zeagle from its Apeks creator, but the reality is that aside from those insignificant differences (DIN wheels?!?!?! they are almost all universal) they are still damn near the same reg.
