Good day all. In reference to this post by lain I'd like to purchase the expansion o rings. I was wondering if anyone has done this and if you would recommend replacing the rider rings or the compression rings while "in there"? Is there anywhere I can purchase just a few o rings? I am under the assumption that Rix wants a minimum order. I have read that Rix disguises their o ring part #'s with a few extra or less #'s, but I am not an o ring guru, so I don't know how to match them. @Zef you're pretty good with o rings.. do these #'s below make any sense? I believe it's just regular viton 90 duro. @rsingler I was told you might own a Rix? Or have in the past? You're a wizard with all things scuba.. maybe you have some wisdom?
I have a minor issue with some blow by coming from the bottom of the 2nd stage. It's been like this since I aquired the compressor 2 years ago. Not a lot, doesn't seem to be getting worse but enough I want to do something about it. I need to give it some TLC so she'll last for years to come.
The o ring part #'s from Rix are;
1st Stage -
123-230-5
2nd Stage -
123-210-5
123-313-5
Any help would be greatly appreciated. I have yet to find anyone that has a vast supply of pictures inside the Rix.

One other point worth consideration is to occasionallly remove the centre bolt and to turn the inner bearing race (the siiver inner part) 30/60/90 or 180 degrees. this presents a "fresh face" to the backside of the rod end bearing housing and ensures even wear over the entire inner race as opposed to wearing just one "face" Contact Area" and allowing excessive wear in one point (at the opposite end from the piston rod) By rotating the race a bit at a time you extend the life of an quite expensive part.
I would NOT do it every 10 or 25 hours but certainley take a look at 50 and while your at it clean the whole inner race of the rod end bearing and check for wear areas..
Now here is the kicker.
DO NOT yank (remove) the whole piston assembly out of the liners, your just cleaning the end bearings, but if you do, dont yank the thing out and be careful not to get grease onto the compression rings.
Then while you are at it you may as well just replace the piston 0-rings behind the compression rings just on the 1st and 2nd stage (NOT the 3rd) Doing this will extend you compression ring life. Dont do it on the 3rd stage you will damage the rings more by removing them. Just the 1st and 2nd.
Doing this also help reduce blow by and increases the interstage pressure thus reducing the compression ratio, reducing heat and increasing flow rate.
Also if you do just change the 0-rings out and put back the old compression rings also check the 0-rings for "scuffing" if you see too much scuffing your not changing them enough conversly when you stop seeing scuffing your changing them too often.
