Radium Engineering 10AN ORB To .75in Barb Roll Over Valve | Universal (20-0594)

A vent that flows air must also refuse fuel when the car ends up on its roof.

The Radium Engineering 10AN ORB to 0.75" Barb Roll-Over Valve does both jobs: in normal orientation it vents freely, and inverted it closes, preventing fuel escape through the vent line in a roll-over. The 10AN ORB end threads into the tank or cell port sealing on its O-ring, and the 3/4" barb takes clamped vent hose.

What You'll Feel

• Roll-over security in the vent circuit, fuel staying inside when it matters most
• Free-breathing venting in every normal driving attitude
• A positive O-ring seal at the tank port, hose clamped at the barb

Features

• Roll-over valve: vents normally, closes when inverted
• 10AN ORB (7/8"-14) thread with O-ring seal; 0.75" hose barb
• All fuel types including E85

The Details

Sanctioning bodies require roll-over protection in fuel venting for good reason, since a breached vent line feeding fuel onto a hot car is the fire scenario rulebooks exist to prevent, and the valve is the passive answer: gravity-and-orientation actuated, no wiring, no failure modes beyond keeping it clean. Mount per the valve's orientation requirements so normal venting flows and inversion closes, route the vent line per Radium's rising-loop rules, and the circuit satisfies both the physics and the tech inspector. O-ring lubricated at install; hose clamped with spring or EFI clamps.
