I have a working ball pressurizer. Thanks! Here are a few things I learned. Valve extenders vary. You want one with a smooth barrel. Take your valve extender and your threaded piece of metal that attaches to the ball-lock connector with you to Home Depot, if that's where you get your plastic tubing, to make sure you get a piece of tubing that fits. The tubing size that fit my valve connector was slightly big for the size of the threaded piece. Solved with super glue. It takes a lot of pumping (possibly because I only have 30 balls I want to maintain. I purchased an electric pump - much much better.
The truck tire valve I used demonstrates from other video but got stuck to pumps air inside the keg. Is it truth you able to injected the air inside the keg?
I'm trying a Schrader bike valve - I'm thinking this is not the best choice. You have to scrape off the rubber that surrounds the valve (with rubber, does not fit 3/8 inch tubing). Then you have the issue of sealing a very rough surface (the valve) with the plastic tubing. The glue I used last night didn't hold. I'm going to try epoxy but if that doesn't work I'll try the valve extender you mention in the video.
The system works, but the balls are not getting pressurized. I kept 15 days with 34psi, but no luck. Ok some balls may be bad but looks like none are getting pressurized. I check the pressure at the end of 15 days and still there..Any idea ?
Tennis balls are around 12psi, 12psi difference from atmosphere which take some time for air to escape. With 34psi, you create 22psi difference on the ball then it will take forever to pressurize. Try increasing pressure for faster output but not too much for your safety
Sorry, you said a ball lock type of keg attaches to the air hose easier? Can you confirm this? It is well worth the $20 extra if so. Hell it would be worth even $50 more
Awesome video man! Quick question though…when pressurizing the chamber, I noticed that I’m hearing and feeling “popping” inside (at around 30 PSI). Are the tennis balls bursting? 😲 The balls are about a year old.
Could you please spell the connectors/parts that you did use (e.g., "amafelton Connector" at 1:54)? I would like to buy them here in Germany and I have trouble identifying the right ones (even as a German, I have no idea of beer brewing, surprinsingly). Thanks a lot!

The end is barb, not MFL. I prefer a lid with a manual relief valve. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6RyVUdEfL9Q.html&feature=emb_logo
Corny kegs are designed for working beer pressures of 60-70 PSI which means they are tested to well over 100 psi. There is a relief pressure valve at 125 psi. To relieve pressure, you just have to depress the pin in the middle of the valve or you can just use another MFL connector without a hose attached.
It depends on what you are using. An air compressor takes about a minute. Bicycle pump will take longer, depending on the pump. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iyan0v5Gh_o.html
Hi, great idea and thanks for sharing - I managed to get all set up and put 60 used balls ( most of them are flat) inside the keg and left for 24 hours however I barely notice any change; balls are still flat. How long in average should I leave the balls inside the keg to re-pressurize ( 1 day,2 days, etc) ? How long balls will hold the pressure once you take them out a start using it ? Do I need to put them back inside the keg after each play? Is 30 PSI the ideal air pressure to put inside the keg in order for the balls to bounce like new ? Thanks !
ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iyan0v5Gh_o.html This guy reckons 32 pounds for 2 weeks although some people say that pressure could collapse the balls.
I brought the "Viair 92839 Inflation Valve for 1/4" Air Line Compression Fitting". Do you think this valve will work? If not would you please repeat what kind of valve do you use here. Thanks again
You filled that with 60 psi through THAT clear poly hose? Yikes! Then again you can play tennis with only one arm 😁. Anyway that's a good vessel except for the removal of only one ball at a time. I made one from a discarded propane tanks and threw it across the street after getting so frustrated trying to empty it. I couldnt stand that. I suspect the opening would need to be able to allow a three ball triangle to clear in order to pour out. Maybe bigger?
It definitely should not be filled to 60psi. Tennis ball cans are pressurized 12psi over ambient atmospheric pressure. 25-32psi is what you need for re-pressurizing. 14-20psi just to maintain freshness.
How long does the re-pressurized effect last for you? Dependent on the quality of the ball I would expect. Have you found any ball in particular to take better to the re-pressurizing process than others?
It depends. Some balls just don't pressurize well. I've found the best success with quality balls like propenns and penn atp. You can actually pressurize them too much and they will be bounce really high. It is actually better for maintaining balls. If you put newer balls in there between playing, balls will last until the fuzz disappears.
@@rockbox1190 The maximum pressure used should be around 28 psi. At around 29 psi the tennis ball will actually collapse. If you exceed that pressure you can actually hear the ball collapsing. That is why higher pressure does not work. When the ball collapse the rubber will be distorted and never reestablish their round shape. That is another reason not to overload the keg. Leave some space for ball expansion. If you bounce the pressurized ball and notice that they bounce at weird angles, that is telling you that you have overfilled the keg. Time to full pressure depends on the original pressure in the balls. Please remember that new balls are only pressurized at 12 psi. My experience is that 2 or three days are usually sufficient to restore the bounce. You can check with the USTA specifications using the drop test. Tennis balls when dropped from the height of 100" should bounce within the range of 53"-57".
@@nmrtexas Tennis balls are made with an internal pressure of 14 PSI and packaged in a pressurized can. Pressure is released when you open the can. Once this occurs pressure inside the ball will now escape through it's porous rubber. During play each time you hit the ball it will force the internal pressure even more.
