Pneumatic couplings are devices used to connect and disconnect air hoses in pneumatic systems. They allow for quick and easy attachment of tools and equipment, ensuring a secure connection that can handle high-pressure air flow. These couplings are commonly found in industries that utilize compressed air for various applications, such as manufacturing and construction. Typically made from durable materials like metal or plastic, pneumatic couplings come in various designs, including quick-release and threaded types. Their primary function is to facilitate the efficient transfer of air while minimizing leaks and maintaining safety. Proper selection and maintenance of these couplings are essential for optimal system performance.
