Honeywell Zone Valve o-ring size?

nj6964 Member Posts: 22
I had an o ring leaking on a 3/4 Honeywell zone valve. I had an old one that I borrowed the o ring from for now. However, I can’t find the exact size of this o ring anywhere online. I see a ball and o ring kit for $30 which seems crazy when all I need is the o ring. Anyone know the size or have a good source? Thanks!!

    Most automotive supply places have O ring assortments. Usually they can match up a ring for you.

    Hydraulic repair shops have a much larger assortment of standard and metric sizes. Some shops have O-ring kits that you cut the length and super glue the size you need.

    If 30 bucks includes shipping it may be less $$ then chasing one down?
