Podavelle AN6 Male Rollover Vent Valve — 6AN (9/16-18) Aluminum Black, PTFE Seals for Fuel Cell

Podavelle's 6AN male rollover vent valve is a compact aluminum safety vent that prevents fuel escape during a vehicle rollover while allowing proper tank ventilation under normal conditions.

Designed for motorsports and performance fuel systems, this AN6 (9/16-18 UNF) male flare rollover valve combines lightweight 6061-T6 aluminum construction with PTFE sealing washers to deliver reliable shutoff in inverted conditions and steady breathing during regular operation. It installs into fuel cells or tanks where an AN6 male fitting is required and is compatible with gasoline and alcohol-based fuels. Professional installation is recommended to ensure correct function and sealing.

How does this valve stop fuel from leaking if the car flips?

The internal mechanism closes when the valve is tipped significantly, blocking the flow of liquid fuel while leaving a path for vapor or minimal air movement if needed. That mechanical shutoff reduces the chance of fuel running out of the vent point when the vehicle is on its side or upside down.

• AN6 male flare (9/16-18 UNF) connection for direct tank mounting
• Sealing washers (PTFE) to prevent leaks at the thread interface
• Gravity-activated internal closure that reacts to inverted orientation
• Compatible with gasoline and alcohol fuels used in racing and street applications

Will this valve allow my fuel tank to breathe during normal driving?

Yes — during regular operation the valve remains open enough to equalize pressure and prevent vacuum from forming as fuel is drawn from the tank. Proper venting helps avoid fuel starvation and allows evaporative gases to escape to a designated breather or catch can setup.

• Designed to prevent pressure or vacuum buildup in the tank
• Maintains airflow for steady fuel flow to pumps and carburetors
• Works with standard breather lines and external ventilation components

What materials and compatibility should I expect from this Podavelle fitting?

The valve is machined from 6061-T6 aluminum to keep weight low while offering corrosion resistance suitable for performance environments. PTFE sealing washers are supplied to improve thread sealing, and the fitting is chemically compatible with common gasoline and alcohol-based racing fuels.

• 6061-T6 aluminum body for strength and light weight
• PTFE washers included for reliable thread sealing
• Rated for gasoline and alcohol-based fuel blends

How do I install this AN6 male rollover vent valve safely?

Installation requires matching AN6 port threads in your tank or a compatible adapter and should be carried out by a trained technician to ensure proper sealing and orientation. Tighten to recommended torque for AN fittings, use the supplied PTFE washer, and route vent lines to a safe location or catch can as part of the overall fuel ventilation system.

• Install into AN6 (9/16-18 UNF) female port or adapter
• Use PTFE washer supplied and follow torque specifications
• Have a professional confirm orientation and system routing

Who is this for? Podavelle's 6AN male rollover vent valve is intended for racers, custom fabricators, and performance car or off-road vehicle owners who need a reliable rollover protection vent that integrates with AN6 fuel fittings. If you run a fuel cell or an aftermarket tank and want a lightweight, fuel-compatible vent that reduces leakage risk during a flip while maintaining proper tank breathing, this valve is a practical addition. Note: no installation instructions are included; professional fitting is strongly recommended to ensure safe, leak-free operation.
