Model
Once you start browsing the options, you will find that there are two different models to choose from - single-head air chucks and dual-head air chucks.
Single-head chucks have a single-head mechanism. They are usually made of durable steel, just take them out of the box and inflate. On top of that, many single-head chucks also feature a locking mechanism that allows you to easily secure the seal throughout the inflation process.
PSI range
Air chucks have a specific pressure range they can handle without issue. Be sure to find a chuck that matches or exceeds the PSI rating of the hose and compressor.
Material
Make sure you're looking for air chucks that are made of high-quality materials and that will last a long time without any issues.
