Radium Engineering Roll Over Valve Universal 10AN ORB to 19mm Barb

Radium Roll Over Valve – 10AN ORB to 3/4" Barb

The Radium Engineering Roll Over Valve is a safety-critical fitting for any build running an engine vent or oil catch can. CNC-machined from billet 6061 aluminium and sealed with FKM (Viton) o-rings, it provides reliable fluid containment if the vehicle ever inverts or rolls over. In normal upright operation, air flows freely in both directions for unobstructed crankcase venting. Rotate the fitting more than 90 degrees from upright and it shuts automatically, keeping oil where it belongs.

This listing covers the Radium Engineering Roll Over Valve in a 10AN ORB to 3/4" barb configuration (SKU: 20-0594). It is designed for use on engine vents and catch can vents, and is compatible with the Radium Engineering Air Filter 19mm ID (P/N: 18-0042, sold separately).

Important: This valve must always be mounted in the vertical upright position for correct operation.
