Can my Mares Abyss be used with Nitrox?

According to Mares, I can, but only up to 40% Nitrox. I must say,
they didn't sound too convincing. What does everyone else think?

TIA!

The most common nitrox mixes are 32% (which I use) & 36%, so I wouldn't
worry.

Nope, sounds totally standard to me. Most manufacturers only warrant their
regs for mixes up to 40% - anything above that requires the equipment to be
in O2 service. Anyway, why would you want to use mixes above 40% for back
gas? I can understand it for deco bottles but see little point in running
mixes richer than this for extended bottom time due to the depth limitations
such mixes would impose...

I don't know, but you better make sure your BC is Nitrox ready. You don't
want the Oxygen to eat holes through the rubber, or, God forbid, explode on
the surface from the spark of the inflator mechanism.

Yes. No problem.

What makes you think our thoughts are better than those of the manufacturer?
Most regulators are safe for use with nitrox up to around 40% provided they
are serviced regularly. Most manufacturers and, consequently, most divers,
think that means annually. Since it's a condition of my warranty, that's
what I do. High PPO2s can increase the rate of deterioration of some
materials used in some regulators. More and more often, regulators come
from the factory with parts suitable for use with pure O2, but even those
that don't, are normally considered fine for normal "recreational" nitrox
use. Those that are not, are identified by the manufacturer.

I have read this thread with interest. I am wondering if the Titanium Abyss
is safe for Nitrox up to 36%

There is no reason a Ti regulator would be incompatible with
EAN mixes up to 40%...Atomic Ti regulators are all compatible.
mine have been used with up to 43% with no problems...hundreds
of times.

The problems with Ti are pure O2 a near pure O2 at high pressures.
i.e. Ti in second stage is not a problem with any mix. It's the first
stage that can be a problem.

safe diving,

thanks for the reply. I really wasn't thinking of using pure O2, except may
as a deco gas later on.

Because we don't let lawyers run our lives?
