Scubapro O-ring Sizes

[Hawaii Treasure Finder]

I received the poppet orings mentioned in post #334 today. Looks like a winner, they pass the bounce test and to my eye appear in good condition and size match. When performing the bounce test, I sealed the LP seat with my index finger as that ensured a solid seal to perform the test.

Hi Kupu, yes, you were right on that - thanks much for the link and test... Will get an order in. Best HTF

Thanks for the assistance to all tracking down where to buy the tiny orings for the G250 poppet.
For all of those looking for a place that sells the 1mm x 2.2mm oring, I used www.Oringsandmore.com . The price is $2 for 50 orings. Specifically, Metric Buna O-rings 2.2 x 1mm Price for 50 pcs

Awesome, thanks for the pdf - nice to see a summation all in one place! This is marked 2008 - any updates to newer regs? Thanks

Would love to see that for MK25 Evo and A700!

Can you get 01.050.351 O ring micro adjuster G260? Cheers.

Your O rings would be easier to find if in numerical order per brand. Also on some items you have the SP part number in bold black numbers at the top of description but on some it's in tiny blue numbers at the bottom.

Any chance you'd consider offering quantities of 25? 50 is a lot for the average DIYer. Cheers.

That is a -903
SP calls for Ni 70
However, there's nothing wrong with using EPDM (longer shelf life.)
McMaster has EPDM 70 for a pack of 90 for $6.56
McMaster-Carr

or if you want Ni

McMaster-Carr

pack of 100 for $4.16

If you're putting a kit together you'll want the exact size, but for your personal regulators (don't tell anybody) I think you could use a -011 in that application and no one would know.

Thanks a bunch Robert, yes, for kits I'm putting together so I'll want exact sizes. You'll be hearing from me shortly. Cheers.

BTW the second link shows 90A duro?
