nitrogen filled shocks, gas types?

[nicksamaniac]

Hi all,
1stly, I posted here as it kind of applies to most patrols, gq to gu.

As the title suggests, I have a set of serviceable shocks, amada xtreme.
I had a leak from 1, I re-sealed it, gasssed it to 120psi all good!

Then I followed up with checking pressures on the remaining 3, only to find they're all below spec,
So nitrogen I can get, I use it at work for hydraulic accumulators.

But I also have at home a bottle of argon for my tig, which would be easier to use obviously!
After a bit of research, I cant find a real reason not to use it, I found tables for pressure coefficient at temp for different gases, a table of materials (seals) that are or aren't suitable in the presents of argon,
They're both clean, dry, non toxic, non flammable, stable gases,

Im not wanting to rent a bottle just for a few hundred grams of gas per year at best?

So? Anyone have info or real world feedback on the subject?
I have found in the usa alot of people have used it, in fox and king shocks, but I dont want to wreck my shocks if its not going to work?
Cheers.

Just a pic of 1 table I found

And a suitable and not suitable material list

What do ppl use in motor bike tyres and plane tyres
You could run say argon in your tyres and see if any differences in temp occur

Well as of today im topped up with Ar.
I'll report back with any significant changes.

Sorry mate I don't have an answer but I'm bloody interested in your findings as I run the same shocks.how many kms on your shocks?

[nicksamaniac]

They're roughly 9000km, 1 was leaking from the banjo pivot on the shock body/cap where it screws in.
so far they feel and drive the same at 120 psi of argon, considering the highest was at only 80psi when i checked them all.

just an update guys, shocks are still working fine
(apart from my front left, which is still leaking from the main body/cap)
but no seal deterioration as yet from using argon? that i can see.

if my front continues to leak badly im going to upgrade to fox, eye-eye shocks and modify mounts to suit.

alls good so far....

I should test mine they have done about 20,000 I'd think

Return the leaking one.
