3M / OS header O-ring size

[Earl Vincent]

I just changed a set tonight after 50+ flights and they were still in pretty good shape, I do not wait until they start to leak but then
I get the used ones at work for free, after they come out of a compressor they are as good as new ones. put a little Mobile 1 on the
o-ring and the seat of the header seems to let it rotate and not break.
