The Swiveling PCV valves listed below are not compatible with standard catch cans and standard Fluid Lock® catch cans due to depth. They are compatible with all Radium Competition Catch Cans and Radium PCV baffle plates. They will thread into any other 10AN ORB female port as well, but that port must have an extra 0.26 inches of clearance after the threads.

OVERVIEW
Radium Engineering universal PCV (positive crankcase ventilation) valves. These are used when the OEM PCV is removed, needs to be moved to the catch can outlet, or for engines that may not already have a PCV system.
HOW IT WORKS
Just like an OEM PCV valve, the Radium PCV valve's internal plunger dynamically meters the appropriate amount of crankcase vent airflow based on the engine load. Proper PCV valves prevent the vacuum leak that a check valve would create at low loads. In the event of a intake manifold backfire, the PCV valve closes preventing combustible vapors from igniting in the crankcase. In turbocharged and supercharged applications, the PCV valve will close in boost to prevent positive pressure from the intake manifold from entering the crankcase.
