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 
on hand?

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 
James, and thanks to you all for listening.
