16 gauge silicone wiring, that's right, the noodly wiring. pull the copper wire out leaving just the sheath, use an exacto knife to cut approx 1mm of a wee wide ring from the wire and voila! I had spare wiring from previous builds laying around, wire that unkikely get used again, took 5 min and I now have dozens of orings for all my fill valve for practically nothing cost wise.
