O-ring advice needed - ordering from allorings.com

[Al in Arkansas]

I'm looking to order o-rings from allorings.com or some similar place.  I confess in my ignorance I've having trouble navigating their website.  I don't really find a place for ordering the specific part numbers I found referenced in the tech archives.  Part # B1000-036,
Part # B1000-226, Part # B1000-129
I also find that the selection of materials to be more information than I am qualified to choose from.
Advice appreciated.  I don't really want to pay the stealer's price on my next set.

Thanks - Al

Try a local O ring supplier. Might be a hydraulic shop or seal shop. It's a #123 and get either viton or silicone.
