Apex Oxygen Clean Regulator Service - DIY

[Ahereng]

Yes. For all practical purposes they are O2-clean when new.

Sorry for opening up an old thread. Are you guys using regular Apeks first stages for O2?

Yes. Unless you have an older service kit, all the Apeks service kits (and newly shipped regulators) use O2 compatible components. I think Apeks only states that their Green XTX/DS4 DIN can be used with 40 to 100%, but there is no difference between that regulator and a standard XTX/DS4 other than green color parts.

Yes. I have an assortment of DST’s and DS4’s mated with TX, ATX and XTX seconds that I use for my deco regs and bailouts. I clean all my regs the same and don’t put specific regs on specific bottles. One day a reg might be on a 32% bottle and the following weekend it might be on a 100% bottle.

Hi guys ! I know this is an old thread sorry
In France we are supposed to use M26 connection for nitrox>40% and i'm planning maybe to buy regs for deco but not sure yet between DIN or M26 connection as some tech dive centers don't like and keep using only DIN and i also dive in foreign countries
My question is , if i'm using an Apeks first stage with M26 connection (or DIN) and i'm buying the DIN (or M26) handwheel/connector shaft to switch between the 2 depending which diving center i'm going to (just have to screw/unscren with allen key if i understood well) , is it ok ? Of course both connection will be dedicated to deco and as a belgian instructor told me, from when the first stage doesn't have its cap or connected to tank, it's not fully o2 clean anymore with ambiant air" so ..

This would be the DIN kit i could purchase :

Apeks DIN G5/8 Handwheel and connection shaft in a set (AP0211)

That's definitely a possibility.
If you don't mind a bit of added length to the regulator, you can also quickly convert it with an adapter such as this.

Do keep in mind that it adds another point of failure with the extra O-ring. It does have the virtue of not needing to play around with the hex key, as ideally the handwheel retainer should be torqued to specification (20Nm on most Apeks models-A bit low if you ask me, but it is what it is...)

I was thinking about the convertor at first but i don't like the idea of that added length/failur point and depending which way i use it (from Din to M26) some french centers could still refuse it i think , so for some extra bucks it will be a full dedicated thing . I just mailed the shop from the product link if i'll have maybe to change the o-ring, other pieces or not, as the DIN kit ain't a specific nitrox product , even if i think Apeks kinda Always sell o2 clean kit

Hand tight should be ok shouldnt it?

Considering people generally ignore everything to do with M26 you could consider doing the same

An absolute fall back, would be to carry the M26 wheel, also the adaptor, with the appropriate tools

A torque wrench is not required

What are you talking about this time chief, what failures, where and when did a din or any other oring fail

ideally the handwheel retainer should be torqued to specification (20Nm on most Apeks models-A bit low if you ask me, but it is what it is...)

So it is not ideal nor is it what it is and if you think it should be torqued to a higher spec you should say so


So back to reality

We are where we are and foot pounds is where are is!

Why would i buy/take the adaptator if i've the full wheel/connection ?
