What is the best quality O-ring manufacturer / product?

[joerush25]

I want to buy O rings for my keyboard and I'm looking for recommendations on the best quality you can buy

Thanks

This is not a product where you are looking for "quality." They are really just cheap, generic, rubber o-rings.  Any outlet that sells keyboards or keyboard supplies will have them and brand is not going to be important.  What is important  is the thickness of the ring because this will determine the length of your keystroke.

They come in several sizes and they are cheap enough where you can buy 2 to make a decision.

There is also hardness because many of the generic ones made for various industrial purposes tend to be quite hard.

I would start with the thinnest and softest ones that you can find.

IMHO, softer the better, you want silicone,

They should be labelled for this purpose or sold by a company dealing with keyboard products and not a thousand pack of some plumbing seal that just happens to fit.  This way at least 1 person before you has deemed them suitable to be a keycap dampener.
