DIN plugs

[ScubaSixString]

All,

I have an Aqualung Titan LX with a yoked first stage.
I am planning on converting it to DIN down the road a bit, but in the mean time, have any of you had any experience with DIN to yoke plugs. 200 bar manifold ( i heard they cant be used on the 300 bar versions).


Thanks

You mean an "insert" not a plug? It is only for 200bar DIN valve, not 300 bar. The number of thread is different....

Yeah.... inserts is what i meant. Any problems with leaks or anything like that?

No, I don't have any problem with 200 bar... Even I put 4000 psi on the tank through the insert. The o-rings show the starts of detorioration though. Here are some pictures of mine.

EEEEP!!!

Is this the extrusion they speak of for the reason on requiring DIN for HP valves?

 

[Hoosier]

Yes..... Yoke can't hold it.... Another failure point!

I don't think this is extrusion... Extrusion, as I understand it, is when the o-ring pushes out past the metal flange(s); if you're lucky, the o-ring may just stretch and not be damaged.

Hoosier, is that fuzzy stuff actually o-ring material? Are your o-rings being somehow abraded? Except for installing and taking off, these aren't dynamic o-rings...

And why, exactly, are you using 4000 psi with a yoke? :11:

SSS, you should be fine with the inserts for now, with a 200-bar valve. Only weak point is the o-rings -- compared to a yoke valve, you have an additional o-ring (failure point) with inserts ... If the insert is kept in the valve, you have one o-ring exposed, like with a yoke valve. But if you take the insert out and keep it elsewhere, you have both o-rings potentially exposed. Keep spare o-rings!

Oh, and don't forget to pack an appropriate hex key wrench.
