Podavelle AN6 Inline Rollover Breather Valve — Female to Male, Black Anodized 6061-T6 Aluminum, Gravity-Actuated Seal

This compact AN6 inline rollover vent by Podavelle combines corrosion-resistant 6061-T6 billet aluminum construction with a gravity-actuated check ball to stop fuel from escaping through the vent line in the event of a rollover. Finished in durable black anodizing, the fitting connects an AN6 female line to an AN6 male line and is compatible with gasoline and alcohol-based fuels. It is designed to maintain proper tank ventilation during normal driving while providing a fail-safe closure when the vehicle is upside down.

How does the rollover breather valve protect my vehicle during a rollover?

The valve contains a small internal check ball that moves under gravity to block the vent passage if the orientation of the vehicle inverts. When the car flips, the ball seats and prevents fuel from flowing out through the vent line, reducing the risk of spillage. In normal upright operation the ball rests away from the seat so vapor and air can pass freely.

• Gravity-actuated check ball seals vent when inverted
• Reduces fuel escape through vent lines during rollovers
• Allows normal venting while vehicle is upright

Will this Podavelle fitting fit my existing AN6 vent lines?

This part is an AN6 female to AN6 male inline fitting, so it mates directly to standard AN6 hose ends and adapters. It is intended for in-line installation between sections of AN6 vent or rollover hose. Check your hose ends and adapters to confirm AN6 thread/size compatibility before installing.

• AN6 female inlet and AN6 male outlet for direct compatibility
• Plug-and-play between AN6 vent hose assemblies
• Suitable for vent lines on aftermarket fuel systems and tanks

What materials and finishes are used, and why do they matter?

The valve body is machined from 6061-T6 billet aluminum, a material known for good strength-to-weight ratio and corrosion resistance. A hard anodized black finish adds surface durability, chemical resistance, and a low-gloss appearance. Those material choices help ensure long service life in automotive fuel environments when used with compatible fuels.

• 6061-T6 billet aluminum body for light weight and durability
• Black anodized coating for corrosion and wear resistance
• Compatible with gasoline and alcohol-based fuels

How should this valve be installed and maintained?

Professional installation is strongly recommended because correct vent routing, secure AN fittings, and proper hose selection are critical for safe operation. Routine inspection of the fitting and vent hose for leaks, corrosion, or debris will help maintain reliable performance. If the valve shows damage or the check mechanism is obstructed, replace the unit rather than attempting field repairs.

• Install inline between AN6 vent hose segments using proper fittings
• Inspect periodically for leaks, contamination, or wear
• Replace if the check ball or housing is damaged or obstructed

Who is this for: This Podavelle AN6 inline rollover breather valve is ideal for motorsport enthusiasts, custom fuel-system builders, and anyone upgrading fuel tank venting on performance cars, race cars, or kit vehicles. It’s suited for applications that require AN6 vent plumbing and demand a compact, gravity-sealing safety device compatible with gasoline and alcohol fuels. Because installation affects safety, individuals unfamiliar with fuel-system work should seek a professional installer.
