Help! Anybody know the o-ring size for an Outlaw/SPA fill probe? Thanks

Take that probe and old o-rings to ACE Hardware check out and match up yours in their plumbing faucet section. They have drawers of many different sizes of o-rings. Make a note what size matches so you know next time. Buy several for spares.
