Thanks you very much for the offer, but unfortunately at this rate, the o-rings would split and crack before they end up on a mower.
I don't know about that Tyler. I got some Nitrile rubber o-rings that I had for about 15 yrs now and they are still in good condition. The problem is they are assorted size in both metric and SAE; therefore, I am running the commonly used sizes and the rest will just get thrown away some as I get a couple new assortments in.
It is the exposure to the fuel and other environmental elements that causes the short life spans here.
