Purpose: In marine applications, flame arrestors are crucial safety devices. They are mandated by the U.S. Coast Guard (USCG approved, typically complying with SAE J-1928 or UL 1111 standards) to prevent engine backfires from igniting gasoline vapors in the engine compartment, which could lead to a fire or explosion. The “high flow” aspect indicates it’s designed to minimize air restriction, optimizing engine performance.
