G250? Worth servicing?

[buddhasummer]

The photos not so clear but the orifice does have an Oring although looks to be too small. Point taken re oriface, I'll order a new one. Are the stainless ones still available or the same as another model? The red one also has a brass oriface, interesting..

awap, yes, seems strange that both would have the same one if incorrect, although stranger things have happened. The Japanese aren't generally into DIY in a big way and I'd say 99% of divers here would take their regs into a shop for service.

I will try and get a measurement posted of the "mystery" one and the "correct" one...

I don't know that the SS ones are manufactured anymore, but finding NOS in SS is not a bad thing...

I'll measure mine and we can compare, orifaces is that is, actually that sounds just as bad...

Is there a functional difference between these two assembly's? They are both listed as being suitable for a G250...

 

[rhwestfall]

no

either balance chamber will work aswill the old ones you have. They tend to fail when abrasives are captured in the sealing o-ring and the plastic is scratched, hence the wiper o-ring upgrade.

Makes sense, thank you.
