The Radium Engineering 10AN ORB to 0.75in barb roll-over valve is an aluminum catch-can fitting with an integrated steel ball that closes when inverted to prevent oil loss in the event of a rollover or impact. Finished in black anodize, it functions as a one-way protective valve for catch can or breather plumbing, combining a standard ORB connection with a protective anti-spill feature.
