The brass material provides good corrosion resistance, making it suitable for air brake systems, fuel lines, and coolant passages. You typically replace one when the old plug is stripped, leaking, or cross-threaded. This plug uses 3/8-18 NPTF threads and is installed with a standard wrench on the hex head.
