O-ring sets may help. Next tine you pull it out measure OD and thickness. Should match up with something from the set or you can find some misc seals on the web. It's a static seal so not so critical on material (viton, gp rubber, etc). Have a look at the plug for reference.

Best bet is to remove the sensor and measure the o ring and then go here https://simplybearings.co.uk/shop/All-O-rings-and-kits/c4747_5572/index.html?page=1 and buy the o ring to match. You’ll need a micrometer to measure internal diameter and the diameter of the ring material. Very good service from these folks in the past in terms of delivery. As already said, no need to worry about what the rings made of, just find one that matches for size.
I usually buy a slightly smaller one, one to the size I measured and a slightly larger one in case of measuring errors.
