oring exchange

Well done,

!@#$%^

Ok, so I accidentally picked up another conshelf over the weekend. It creeps enough to warrant some attention and I already have a spare HP seat for it. So could somebody hook me up with 1 or 2 -006's, maybe with backup rings?

Herman, don't you have a few of those?

I have most of what the OP is asking for to offer in trade. Plus some others.

No, I don't have a few of them....got a bunch of them, just got a shipment in from McMaster ....and the back up rings to go with them. Viton 006s and burna backups. Be happy to trade/swap/sell a few.
They will fit the balance chamber of USD/AL Conshelf -Titan-SEA-Legend-Royal-Royal Aquamaster-Mistral (new version)- VDH Phoenix and Mares MR12s. I am sure there are others, those are just the ones I am aware of.

I could use some HP gauge orings

2.2 x 1mm is the size you need. Precision associates is where the group bought from last time. 40 dollar minimum. There is enough interest in this size that it will make it affordable for you.

I've been using 2.5 mm x 1 mm to replace the 2.2 mm x 1 mm that go in the poppets of my G250s. So far I've had no problems. I have them in 3 different G250 Graphites. Two of those have had these for a year. The other one has had these for 3 or 4 months. You can get these for $3.38 for a pack of 25. McMaster-Carr

I bought these same ones exactly last week and tried them the day you posted this....I have to say, I didn't like they way they fit. They are too large in my opinion. I'll try to get some of the 2.2mm x 1mm

Any body can trade the 2.2 x 1 ? I have a bunch of O rings to trade.

Did they work on your regs?

I didn't like how they looked either. They do look like its a hoola hoop gyrating around a tiny waist. But I managed to get them into the balancing chamber and so far they've worked fine for me. I may not like how they look but I do like how they've performed so far for me.

It's like master awap recently said to me:

Perhaps you just have to be prepared for some bad ones. Just be comforted by the fact that Scubapro refuses to sell OEM parts to us for our own good.

In conclusion, if it works just enjoy it. It might not work all of the time, YMMV. Also, FWIW, I was looking at manufacturing tolerances for the 2.5 and the 2.2 and when you factor in these, you do have a chance to have a 2.2 be the same physical size as a 2.5 because their tolerances do make them overlap a little bit.

...I have to say, I didn't like they way they fit...

Me neither. They do go in with a bit of persuasion, but it doesn't feel right, and they may possibly wear the balance chamber out a bit more.

I was getting way off subject with my post, so I start a new one:

O-ring experiment

In my last o-ring purchase I failed to order -023s so I would not mind having a few of those, if you have a few to spare PM me with what you need.
