The 3G Exhaust Ball is to be used immediately after every flight. Not just for storage. Secure the plane and insert the 3G Exhaust Ball.
The moment your aircraft engine shuts down, invisible damage begins to occur. Hot air trapped inside the exhaust system rises, pulling in cooler outside air full of moisture through the tailpipe. That creates a natural current, carrying water vapor into the engine and coating both open cylinders and closed valves.
When that current of outside air reaches metal components, it increases the risk of corrosion. Over time, the cooler air, and moisture can cause shock cooling, warping, and wear and tear, making engine maintenance more expensive and time-consuming.
With our made-in-the-USA 3G Exhaust Ball, we’ve engineered a way to block the damaging corrosion process after shutdown. The ball is designed for piston and turbine engines, providing much-needed protection for your investment, whether you’re sitting on the ramp, in the hangar, or storing your aircraft for the season.

The problem with most aircraft is when the engine shuts down. Oil drains back into the sump, leaving your critical upper components more exposed. Without some form of barrier, moisture enters the tailpipe (the path of least resistance) and creates an environment that cultivates aircraft engine corrosion. What does this mean for your bird?
· Camshafts and valves become vulnerable once the oil drains away.
· The higher the humidity, rain, or pollution, the greater the acceleration of chemical reactions on metal.
· As corrosion builds, aircraft performance suffers, reducing the time between overhauls (TBO) and increasing maintenance requirements.
This corrosion issue isn’t exclusive to people in aviation. Many motorsport teams recognize the same problem of blocking exhaust inlets after shutdown. That principle has been reimagined with our 3G Exhaust Ball.

Plugging your aircraft’s tailpipe isn’t enough. By the time you insert a plug, corrosive elements are likely already moving throughout the systems. In many cases, that can seal in moisture rather than prevent it. While you can use breather tubes for some minimal airflow, the tailpipe is the most direct path for humidity.
The trick is to stop airflow before it happens using the 3G Exhaust Ball.
Florida is the perfect example of how this works. Frequent rain and thunderstorms create heavier evaporation. In 12 hours, as much as 1.2 cups of water vapor can evaporate from a single square foot of surface area.
Without proper protection, your aircraft will experience more condensation, evaporation, and damage from corrosion. No one wants a compromised engine, especially when it will drive up repair costs. And worse. Create a potential safety hazard in flight.
Our patented 3G Exhaust Ball is the only aviation-specific condensation blocker designed to work immediately after engine shutdown. When you use this specially engineered tool, you gain the benefits of:
· Blocked Entry: Sealing the tailpipe before any moisture can sneak inside.
· Absorbed Humidity: Residual humidity is removed from the built-in aviation desiccant pack in the exhaust system.
· Prevented Shock Cooling: Reducing rapid thermal change, placing way less stress on valves and cylinder heads.
· Extended Lifespan: The 3G Exhaust Ball helps to keep your aircraft engine corrosion-free, boosting its operational reliability.
We’ve designed the 3G Exhaust Ball to work with all types of aircraft, from private pilots on a weekend vacation to flight school operators or logistics providers managing a commercial fleet. Get reliable engine condensation prevention with the 3G Exhaust Ball.
James O. Says; "Received them in the mail yesterday. They fit nice and snug. Been a very pleasant experience. Great product and interactions".
Rick R. Says; "With my plane always hangared near either Lake Michigan or the Gulf, keeping that exhaust pipe sealed from the moist air is critical. Your exhaust ball does that perfectly. Thank you".
Drew D. Says; Just wanted you to know that I am loving these so far!
The fit was PERFECT! They look great, and I am feeling good about the additional protection.
A very nice addition, sort of trims out the airplane as a bonus - thank you, great invention.

The 3G Exhaust Ball is built and manufactured in our engineering facility in Pioneer, California, USA. It works with piston and turbine engines, utilizing the same premium materials trusted by NASA, NASCAR, and the U.S. Military, which means it can withstand high heat, heavy use, and harsh environments.
We take great pride in building a product focused on aviation safety that improves maintenance needs. Using the 3G Exhaust Ball is a reliable way to prevent corrosion and reduce shock cooling. One small investment offers high, long-term ROI by keeping aircraft engine-ready between flights.
The 3G Exhaust Ball was even featured on Juan Browne’s aviation channel, @Blancolirio, highlighting why protecting aircraft engines from moisture damage is so important. With a patented design trusted by pilots, fleet operations, and aviation experts, the 3G Exhaust Ball is your best way to reduce maintenance costs and enhance engine performance.
Don’t let moisture shorten the life of your engine. Protect your aircraft with the 3G Exhaust Ball, the only patented aviation condensation blocker.
