I’m working on fixing up a 2013 Tesla Model S Battery Pack.
These are the new style Umbrella Valves – ASY,VENTS,GANGED,HVBATT
1517973-00-A
If you are looking for them on Tesla’s parts catalog, they are listed for the 2016-2021 Model S.
My car originally had SIX umbrella valves per battery module bay. Unfortunately, they can fail and let moisture into the battery pack.
These valves are a slightly different design and only have TWO umbrellas per bay, plus a Goretex breather. The rest are solid plugs..
