The 90° Quick Drop in aluminium compressed air piping is a piping connector that is mainly used to achieve a 90-degree turning connection between pipes and has a quick-change function. These fittings are usually made of aluminium alloy, which is lightweight, strong and has good corrosion resistance. Its design makes installation and disassembly very convenient and fast, without the need to use special tools or equipment, thus improving work efficiency. In aluminium alloy compressed air piping systems, 90° Quick Drops are widely used in scenarios where the direction of airflow needs to be changed or where piping in different directions needs to be connected. They can effectively solve the problem of space constraints in piping layouts and, thanks to their quick-change feature, they can quickly replace damaged parts and reduce downtime when piping systems need to be repaired or changed.
