American pneumatic quick couplings are typically made of carbon steel, brass, and stainless steel.
Carbon steel material can withstand higher working pressures, while brass and stainless steel can be used in environments with water, oil mist, and corrosive conditions.
Considering working pressure and medium environment, mixed materials can also be used, such as brass valve bodies, galvanized carbon steel sleeves, stainless steel materials, and locking balls.
Pneumatic quick couplings are classified into three types based on flow rate and port size: 1/4”, 3/8”, and 1/2”, to meet different flow rate requirements.
However, some series currently only have a 1/4” valve body size.
Before purchasing, it is important to carefully distinguish the required flow rate, working pressure, and working conditions and medium. Essentially, all American quick couplings feature NPT threads.
If other threads are required, please remind us in your order.
It is recommended that the working pressure does not exceed 2.0 MPa. For higher working pressures, carbon steel, stainless steel, or mixed materials can be selected, such as brass valve bodies, galvanized carbon steel sleeves, and pipe nipples or plugs. Common sealing materials include nitrile rubber, as well as FKM fluoro rubber, EPDM, and other sealing materials available for selection.
These couplings are commonly used in industries such as air compressors, pneumatic tools, pressure washers, lawnmowers, sprayers, and more.
