Cheap o-rings?

[uzoc]

Trying to get extra 0-rings: 50AR, 4mm reduction (about two hundred) for my two keysets that I'm receiving.
Paid $17 + shipping for 125 o-rings, originally.
Any tips from where to get them cheaper (preferably from the US)?

Found these on Amazon, but they are 0.7" in width (2mm reduction?), correct me if I'm wrong:

@uzoc:
Be careful what you buy. You probably need around 1mm reduction.
Cherry MX TOTAL swing is ~ 4 mm, with actuation point somewhere in the middle.

Very careful, I already have them and use them with no problem.
They are probably a little less in width (I don't have a caliper) but that's what WASD keyboards calls them "4mm width".

These buna o-ring works very well. Also, you can get the 70A for less than 2$ a bag of 100. I use them and I love them.

They are buna o-ring, size is 008 (3/16, 5/16, 1/16). They are 70A durometer, but I like it a lot. Reduce noise enough while not making the bottom out too soft.

At this price, try them and see if you like em or not. Else, well IMSTO's are probably yo best bet if you want 50A or less.

Thanks, I'll try them, what I hate it that I'm going to have various ones until I can guess which ones are 0.4mm!

I think I got it...
There are three that are 3/16 (inside diameter), of the three, the different widths are:
0.07"   ~ 0.177 mm,
0.103" ~ 0.206 mm
0.139" ~ 0.359 mm

The last one being the closest. to 0.4 mm.
I'm going to get 2 of the last and 1 of the first just in case!
Hope this helps people who are trying to figure it out.
While I'm at it, I'll order a caliper to measure them.
