Description
Radium 20-0688 PCV Valve, 10AN ORB to 10mm SAE Quick Connect Male
Application: Universal (10AN ORB female ports, Radium catch cans and PCV baffle plates)
Part Type: Straight PCV valve (10AN ORB to 10mm SAE quick connect male)
Part Number: 20-0688
The Radium Engineering 20-0688 is a universal straight PCV (positive crankcase ventilation) valve with a 10AN ORB inlet and a 10mm SAE quick connect male outlet. Use it when the OEM PCV valve is removed, needs to be relocated to the catch can outlet, or on engines that do not have a PCV valve at all.
Like an OEM PCV valve, the internal plunger dynamically meters crankcase vent airflow based on engine load. A proper PCV valve avoids the vacuum leak a simple check valve would create at low engine loads, closes during an intake backfire so combustible vapours cannot ignite inside the crankcase, and closes under boost on turbocharged and supercharged engines to stop intake pressure entering the crankcase.
Key Features
- Dynamic metering: internal plunger meters crankcase vent airflow to suit engine load
