AN6 Inline Rollover Vent Valve, Female to Male, Fuel Tank and Fuel Cell Breather

Fit this inline in your fuel tank or fuel cell vent line. It lets the tank breathe normally and closes if the car ends up on its side or roof, so fuel cannot pour out of the vent.

• AN6 female swivel one end, AN6 male flare the other
• Ball type rollover valve inside an aluminium body
• Red, black or blue anodised finish
• Mount it upright, as the valve works by gravity

Frequently asked questions

Do I need a rollover valve on my fuel tank vent?
It is a smart safety part on any custom tank or fuel cell, and most race rules require one. Check your local rules and your engineer for road cars.

Which way up does it go?
Upright, with the arrow or flow direction pointing away from the tank, as high as practical in the vent line.

Can I use it with E85?
The body is aluminium with an internal ball and seal. For E85 use, check the seal suits your fuel or ask us before ordering.
