I've given up on trying to find a bulk o-ring/x-ring supplier that will make, or have stock to specs that I request. The current x-rings that I am using in my RCs are not holding up so well. The hardness of the material is just that...too hard, and they don't grip the shock shafts like OEM o-rings. I've contacted a few companies, and got replies/price quotes. Some won't make that small of x-ring, or the price is about $1 per x-ring ...that's after requesting a quote for 500 x-rings
. I hate to think how many I would need to purchase to get the price down around .35¢ per x-ring.
I guess my search will end with me having to buy RC specific seals at premium packaged price.
