Thank you.

aquaregia:
It's the "AS568A Dash No." under "Std", the 1st column of your LHS's chart. Formally, it should read 2-xxx, but we're lazy
Same for the 1st column: it should read 01-050-xxx.

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.

HenrikBPs question made me take another look and I have a couple corrections and additions. Problem is I had different thing written in different places and did not look at all my notes. When replacing o-rings, yuou need to match them up if there is any doubt.

The SP 160 is an AS016, not 015 with application on G500/S600 and Mk15

The SP 157 is an AS 015, not a 014

The SP 184 is an AS 024, not a 023 with application on the Mk7 piston retainer

Addition: The SP 182 look like a AS 023 with application on a Mk200 (and some Oceanic computer battery compartments.

And the SP 168 looks like the AS 019 on a Mk3 piston.


I guess we may have to let this thread stew for a while and then figure out how to do a corrected list and delete the erroneous info.

Probably the best way is to edit the first posts, so it wouldn't mislead anyone.
There's also a little bug in the Excel sheet: I forgot to format the 2nd column as text, so the leading zeros are gone.

Personnaly, I wouldn't mind at all updating the list on a more or less regular basis.
The problem is the ability to edit is gone after 24h. Please, can a moderator make an exception?

Can't edit it. Apparently the permitted time for editing is expired. I'm sure we will be able to work something out when the time comes.

In the mean time, this thread is still much neater than my notes.

Did SP switched some of their O-rings from Duro 85 to 70 in later years? I noticed a slight difference in duro between Superstar's attachment and Awap's compiled list. Not sure if the difference is significant?
