Question by: Shane S on Aug 17, 2025, 7:11 PM
Will this adapter hold up if it gets some battery acid splashed on it?
Answer by: Customer Support on Aug 18, 2025, 9:26 PM
Unfortunately, this adapter isn't rated for environments where it might be exposed to battery acid. You'll want to find a fitting made from a more resistant material for that kind of application.
