Have You Tried This Amazing Ball Spring Plunger?

Ball and Spring Plungers have a variety of uses, from fine work to heavy-duty tasks. They provide the means for accurate force application with their round or pointed noses depending on what type you purchase!

The ball spring plunger is a type of airlock that was used before the popularization of Sanke kegs with built-in poppet valves. This style was commonly employed by homebrewers and it remains an important vessel for secondary fermentation, aging beers in bottles or cans until they're ready to drink!

The inner piece is hollow with a hole in the center, and the outer piece is solid around the hole with a smaller threaded center to accept either a rubber stopper or an airlock. In use, water is filled into the ball nose spring plunger until it reaches the top of the inner tubular chamber. Next, an appropriately-sized hole is drilled through both pieces from one side so that it lines up over this chamber when they are rotated closed by hand. A short length of plastic tubing is then pushed into this hole, which makes it possible to fill or drain air from below without disassembling the plunger.
