Which type of connection is commonly used to join pneumatic hoses?

Push-to-connect fittings are commonly used to join pneumatic hoses due to their ease of use and efficiency in pneumatic systems. This type of fitting allows for a quick connection and disconnection of hoses without the need for tools, enabling users to easily set up or change configurations in a pneumatic circuit. The design of push-to-connect fittings generally includes a mechanism that securely grips the hose while ensuring a good seal to prevent air leaks. This feature is crucial in pneumatic applications where maintaining pressure and avoiding leakage is essential for system performance.

In contrast, screw connections typically require more time and effort to assemble and disassemble, which can be inefficient for applications needing frequent adjustments. Welded connections are permanent and not practical for assemblies that may require disassembly for maintenance or changes. Clamped connections, while they can provide a robust joining method, often do not offer the same level of convenience and speed as push-to-connect fittings, making them less preferred in many pneumatic applications.
