Types of Air Chucks

Closed Flow
Most air chucks use a closed-flow design. This type keeps air from flowing until it is pressed or locked onto the valve stem. These are generally the best choice for an air compressor that features a tank as the compressor doesn't have to work to keep the tank filled as you work.

Open Flow
Open flow chucks allow air to continuously flow through once they are attached to an air line and are ideal for use with a tankless compressor. This type of air chuck is growing in popularity as it’s often viewed as the most efficient type. Many are designed for use with tire pressure gauges.

Clip-on vs Push-on vs Screw-on
Air chucks secure to the valve stem in a few ways. Clip-on and push-on are the most common designs used. As the name implies, a push on air chuck requires you to push it down on the valve stem to begin supplying air. Clip-on models work similarly but feature a clipping mechanism to keep it in place, reducing the risk of letting air leak out. A third type screws onto the valve stem. Screwing into place creates a superior seal but is considered more trouble than it's worth, considering clip-on chucks are very reliable.

Tips

• You’re bound to lose, misplace, or lend out air chucks. It’s worth investing in a few to prevent yourself from winding up in a bind.
• Air chucks are relatively inexpensive, but losing them can still be extremely frustrating. It’s worth investing in a small case or pouch to help you keep track of them.
• You always want a tire to be filled to the appropriate specifications to prevent excess wear, promote performance, and reduce the likelihood of blowouts. Therefore, you’ll want a high-quality tire pressure gauge on hand, if not built right into the chuck.
• Remember, there's a reason a tire went flat. It's best to keep tire or inner tube repair equipment on hand so that you can deal with any punctures.
