Chip Detector (ADC) replacement O-RING size

Does anyone happen to have the O-ring size (and material) for the ADC chip detector? (the O-ring for the quick drain part, not the copper washer).

ADC is long gone, and my plane is in the UK, and I’d like to get a replacement while I’m in the home of imperial sizes (USA). Logistics and finding imperial sizes can be a pain and I much prefer parts in hand rather than having the plane down while I try and chase the proper part.

(And, not ask a friend (again!) for a favor as it’s a somewhat unique cowl removal for two guys who haven’t done it before. Then two guys and a mess as one guy sticks his finger to plug the quick drain recess while the other guy (hopefully quickly) removes the ORing , measures, and replaces without damaging it, and then swaps finger for drain/detector...)

Thanks, Clark
