Off-the-shelf o-ring for Hayward EC-65A bump handle?

[pleasantpool]

Hi guys,

My bump handle is leaking like crazy, and I'm assuming it's because the o-ring has gone bad. I have found the part,

(16 O-ring ECX9611246 3250-F24 $7.00) http://www.pools.com/parts/Hayward-Perflex-DE-EC-65-75_-674

but the idea of paying like $20 for a single oring plus S&H sucks. I'm sure I could find this o-ring at a hardware store, but I don't know how to find the equivalent standardized o-ring size. I haven't taken apart my DE filter yet for the replacement, as I was hoping to have the o-ring ahead of time. This particular DE filter head is a real pain in the butt to take apart (the bolts on top are very hard to fit a socket wrench in, I did it last summer).

Anyway, if anyone happens to know the standardized equivalent of this bump handle o-ring, could you please reply?

Thanks,

Some places like Harbor Freight sell boxes of assorted O-rings for a reasonable price. Most likely, the box would have an O-ring that would work.
