Product Description

The Radium Engineering 20-1808-FL Universal Fluid Lock Catch Can Kit is a **custom-fit crankcase or PCV vent oil catch can solution** designed for engines that use **1/2" (13 mm ID) vent lines**. This 8AN version of Radium's patented Fluid Lock series traps harmful oil mist and blow-by vapors before they recirculate into the intake, helping keep intercoolers, intake manifolds, and throttle bodies cleaner and free of oil buildup. Its advanced air/oil separation and internal baffle design improve engine efficiency and can help maintain consistent performance in both forced-induction and naturally aspirated systems.

Constructed from CNC-machined aluminum with O-ring sealed 10AN ORB ports, the 20-1808-FL kit includes a universal mounting bracket, a variety of hose ends, and 10 ft of PCV hose to support flexible routing in custom installations. An integrated threaded dipstick allows quick oil level checks, while the optional 4AN ORB drain port makes remote draining possible when space is limited. This kit is ideal for enthusiasts building custom ventilation systems or adding a catch can to an existing PCV setup where a vehicle-specific solution doesn't exist.
