Tech diving regulator?

[Rayk]

I am talking about the plastic transparent diagram on the end of the regulator. If this punctured it still works under water? What is this for?

I can’t think a scenario that will be punctured while diving, maybe lack of experience but never seen one. However Scubapro sealed diaphragm first stages has bump cap over the seal.

op is talking about the diaphragm cover on the second stage, not the environmental seal. Gue and some other organisations have this as a mandatory requirement so you can replace the second stage diaphragm or clean it out in high flow environments.

Can you point to this requirement in the GUE standards? I have never noticed it or heard an instructor mention it. Nevertheless, most if not all of the regs being discussed here have that feature, so it's sort of moot.

HOG D1s have gotten me through Fundies and Cave 1 so far. No instructor has made any comment about my regs. Comparable to the Apeks the OP is considering, I think. If I were buying again today, I might get Deep6 for the same reason HOG was attractive: the ease with which I can service them myself.

: the ease with which I can service them myself.

My own opinion;
Imperative for tec diver.

In the ScubaPro universe, if you puncture the seal, you basically have a MK-11....

If you are regularly puncturing the environmental seal on your reg, you have bigger issues you should worry about.

As Halocline said, in the rare event you do break a seal, the reg will work normally and a new seal is part of a service kit. Not something to lose sleep over or compromise hose routing.

The only benefit of turning them out is the hp port position because it pushes over the wing. Is a tiny bit of improved hose routing of the hp-hose worth two exposed environmental seals.. I don't know..

It might not be in the standards or general curriculum, but I've seen it as a requirement with multiple cave instructors. Or atleast discussed extensively wether or not it should be a requirement in caves where big silt could fill up between the diaphragm and the front cover and cause issues, punctures, bla bla bla.

Everyone just assumed op is talking about the environmental seal, which is possible as well, but not clear at all if you see what OP said.
That's why I (perhaps incorrectly) assumed he was talking about the need for a removable second stage front cover.

OP literally said:

'the reg needs removable cap'.
So it could be two things, the front cover of the second, or he wants a plastic cappy that covers his environmental seal.

I mean are you really telling me you've never had anyone make the arguement for the need for a reg that you can disassemble under water? It's one of those topics like hand tight instead of wrench tight regulators that has been beaten to death by now...

Picture of the environmental seal in an Apeks 1st stage.
There is no mistake.

I have a boat load of HOG D1's.... Use them on everything (except for my CCR O2, which already came with a slightly different generic Diaphram 1st stage).

One service kit, instead of many, and can bang out a regulator in roughly 45-60minutes depending on how "well" I've kept it over the years.....

This is a sincere question, not meant to light anyone on fire, but has not there already been some discontinued parts in one of these Hog type brands? And is the volcano orifice non-replaceable? That, if true, is a negative, but then I have a couple of Conshelf firsts that are older than most of you and they have an integral volcano orifice and are good for another 30 years perhaps. But, one of the improvements of the Titan LX first (and Legend, and Core and on and on) was the separate and replaceable volcano orifice of stainless steel. The Mark 17 and Mark 19 have a replaceable volcano orifice and the environmental seal is not directly exposed though that really is nothing of importance. If you gotta have a turret on a diaphragm sealed first, the Mark 19 is about it. Yeah, you pay more for the S but twenty years from now you will likely be able to get at least some support.

Pity only the FSR has this feature.

My Tabatas breathed better than my SPs. Most notably at depths where it would matter.
