Radium Engineering Fluid Lock® catch cans operate as fully closed-loop systems and do not vent to atmosphere (VTA), making them emissions and track legal. They remove oil vapor and other contaminants from crankcase gases before they are returned to the engine, promoting negative crankcase pressure while preventing unwanted oil vapors from entering the cabin.
