Several of my Jandy Valve O-Rings are bad. Having trouble identifying the right size. Pics are below. They're an older 2-way gray valve with 4 screws. Almost every image I can find does not match mine. There are patent nos. on the top which I have googled with no luck. When I measured what I would think the outer portion of the diameter of the o-ring would be, it is 2 3/4". Any suggestions on finding the correct o-ring?
Also, do generic O-rings that are the right size work, or is that a non-starter for these?
