Scubapro O-ring Sizes

[Couv]

Well, rats. That is one annotated file (our first one) that we had issues with from the beginning-including the note to remove a part through the exhaust valve hole.

I do not remember any -9xx being used in a second generation so a -007 must be the correct size.

Thanks.

Edit: I just located what I believe to be a complete Second Generation AIR 2 service kit (my last one) Measuring the o-ring that seals the exhaust button stem reveals that it is as near as damn it to a -007....so there you have it. Master Awap correct as usual.

I found the reason I mislabeled that o-ring too. I lazily assumed the 2nd and 3rd Generation AIR 2 models had the same diameter exhaust stem. I have a 3rd gen button/stem assembly and it does take a -008.

Thanks for clearing things up. Just placed an order for -007.

Hi folks, just joined the team. I've a question for you all : any idea were I can procure Scubapro o-ring P/N 010-50-428 for my MK25 ? Qty could be multiple of 50 pcs.

Welcome to the Dark Side!

I think that is the DIN filter retainer seal. It's a size -111 seal that should be a duro 85-90. If you want to get one in military grade FKM (Viton) the part number would be M82248/2-111 and can be purchased at O-rings, Inc. M83248/2, ORINGSUSA for about .23 each if you buy in quantity.

Edit: I just noticed you are in Italy, if you need to order the seals in Europe, the metric size is:
10.77mm i.d. X 2.62mm cross section.

I used these guys before, they're OK, and they can ship via USPS (US Post), which is a lot cheaper than UPS or Fedex. It takes about a week to get to Europe.

Scubapro uses their own part numbers for o-ring (01-050-xxx) that have little correlation with standard o-ring sizes. I have worked up a correlation between SP part # and standard o-rings sizes for all applications I use in my Mk2/5/7/10/20, 108/109/156/R190/D-series/G500/S600/Air2, as well as hoses and others items. So let me try to get it started and see what we can do. Your comments, questions, and corrections are more than welcome. I'm sure this may get messy but some smart organized guy like couv will probably come along and clean it up. Metric sizes are width x ID.

SP # Std # Duro Note
109 003 70 SPG spool, duro 90 harder to install
117 006 70
126 008 70
127 008 90 I use a doro 70 and it works OK
132 010 70
136 010 90 Mk20/25 piston
137 010 90 Mk5/7/10 I use urathane
138 011 70
142 011 70
144 012 70
147 013 70
152 013 70
157 014 70
160 015 70
161 017 70
162 017 70
177 022 70
179 022 70
184 023 70
193 111 90
196 112 90
211 116 70 D-series switch (round peg in a square hole)
217 117 70
258 214 90
293 902 70 slightly thinner than a 010
322 117 70
323 1x4 70 metric D-series - not yet tested
342 012 70
347 014 90 yoke valve
351 011 70 not sure, could be
351 903 70 ??
375 1.5x7 70 metric, this works but is a bit thick
375 1x8 70 metric. I did not try this but 1x7 is too small
380 015 70 duro 90 may be better
385 109 70
399 1x2.2 70 metric
363 1x2.2 70 metric


It's a start.

Edit: See, told you it would be messy. Spacing lost but I think it is still readable.

Hi would you be able to help with the QD seal/oring SP number 210009112 which I am finding hard to source in the uk please?

The problem is that is a washer and not an o-ring' I believe SB member couv may have found a source. He will probably see this or you can contact him.

That seal can be sourced from McMaster-Carr It is item number 90130a029.

EPDM Sealing Washer, 1/4" Screw Size, 0.500" OD, 0.078"-0.108" Thick
