It has a black one and red RTV slathered around it. Is the green o-ring
of a tougher material than the usual black o-rings made of nitrile? If
not, could I just use a comparably sized one out of an o-ring selection

Thanks Loren, gotta save that one for a sunny day to try. BTW, I
forgot to change the subject line on my last reply to the list, sorry
