Question by: Merle C on Sep 17, 2025, 12:29 PM
Reckon this adapter will hold up okay in a chemical plant environment? We got some pretty nasty stuff floating around.

Dura-Kote plating gives this adapter superior corrosion resistance, so it should be well-suited for chemical processing environments.
