what size are the u.m.i. o-rings??

[infamy]

i need to replace the o-rings on my u.m.i. setup. does anyone have the mcmaster reference # for these? or know what size they are (mainly need the larger one). thanks

Go to McMaster's web site and type o-ring in the search. When it asks for a "dash" number, give it 146 (i think that is the big one). Then choose the compound of the o-ring.
I'm going to order the hardest compound to try out. (Shore D:55) That part # is 9559K184. You may want to try a softer compound.?

Measure the o ring groove to make sure you get the correct ring.
