Scuba Pro G250 and R109 questions

[buddhasummer]

I'm not going to make a specific advertisement for conversion kits as I'm not sure it's worth the effort but if anyone wants one just message me.

No, I'm very sure that those diaphragms are original SP, I have seen them pretty often, but only in black.
The one on the first photo is the first I found translutioned, but that is probably not so surprising looking at this particular G250 body.
On the photo below you see one G250 as I normally know them from the first and, I think, 2nd generation

Intuitively, it makes sense that a thicker/stiffer diaphragm would require more vacuum effort to bend than a thinner, more flexible diaphragm.

Yes, I've seen those knobby diaphragms (black) in a few SP regulators. A quick glance at the part number confirms it is indeed SP.

I have all new stock OEM springs, levers, orifices, S-wing poppets, long crown balance chambers etc. if you need, message me. I'm putting together full kits including all those items plus necessary O rings (and flow vane C clip) for 109/156/G250 conversions if anyone's interested. I have enough parts to make about 10 full kits.

Do you still have parts for 109.

 

[buddhasummer]

No, afraid not.

Six years is a long time

Service kits are easy to find in Europe … maybe @axxel57 can suggest shops

What other parts are you looking for ?

I need the exhaust tee , and s-wing poppet inkl spring and shamber to convert it to BA156, and i would like to change the diaphragm to a blue one

You need to change lever to a G250V lever .141.

Exhaust T are NLA so you're looking for used, good luck, or 3rd party.

Blue diaphragm is also NLA you'll need someone who's willing to part with one.

Spring .216 or .218 you can but new, ditto balance chamber. S-wing poppet is cheaper to buy in a service kit G250/G260 or S600/G250 that as a seperate item, go figure.

Ok, do you know if this diaphragm fits Purge Diaphragm for Scubapro, G-250 as part no 11.261.008
