Collection: Radium PCV Valves

Radium Engineering universal PCV valves for crankcase ventilation systems — used when the OEM PCV valve is removed, relocated to the catch can outlet, or on engines without a PCV system. The internal plunger dynamically meters vent airflow to engine load, closes during an intake backfire, and closes under boost on turbocharged and supercharged engines.

Straight 10AN ORB valves suit all Radium catch cans. Low profile swivel banjo PCV valves need an extra 0.26" (6.7mm) of clearance and suit Radium Competition Catch Cans. Every valve comes fully assembled with a 10AN ORB FKM O-ring pre-installed. Genuine Radium Engineering, supplied by Coore Australia.
