My local shop gave me some info about orings and need some clarification here

[Nikelu]

They told me that these http://www.e-shop.gr/images/PER/BIG/PER.814932.jpg  have outside diameter of 8.0mm, inside diameter 4.8mm and thickness 1.6 mm . I'm kinda new to this stuff so I only heard of 0,2 and 0,4 orings. What do the numbers mean ,mason? Is the double oring mod good? And which cherry switches go good along with orings?

hmm i'm not too sure

.2 and .4 mm are thicknesses. That's what WASDKeyboards offers.

So the diameter of the ring I assume would be 8.0 to the outside. However inside the ring where the stem would go is a diameter of 4.8mm.
There is a difference between the outside and inside diameter of 3.2mm due to the 1.6mm thickness of the ring.
Don't know if that clarifies anything.

Well.. not exactly.

.2 and 0.4mm are the travel reduction caused by the 2 thicknesses of orings they sell when used with their own keycaps, although that's largely a meaningless metric since different keycaps made by different companies will give different travel reduction with the same orings.

The ones you are looking at seem to have the right dimensions to work well on most MX switch caps.

I can confirm this ^

WASD 40A-L (red/pinkish) are ~1.5mm thick
WASD 40A-R (blue) are ~1.8mm thick
