Radium Pcv Valve 10An Orb To 3/8 Barb

Radium Engineering valve for PCV (positive crankcase ventilation) systems. Do not mistake this for a simple one-way check valve. The PCV valve's internal plunger dynamically meters the appropriate amount of crankcase vent airflow based on current engine load. Proper PCV valves prevent the "vacuum leak" that a check valve would create at low loads. Also, in the event of a backfire, the PCV valve prevents combustible vapors from igniting in the crankcase. 20-0530 SPECIFICATIONS Aluminum: 6061 Type-II Anodized Sealing O-rings: FKM and Silicone Inlet: 10AN ORB (7/8"-14 threads) Outlet: 3/8" Barb (9.5mm)
