These components, defined by specific dimensions, facilitate connections within pneumatic systems. An example of their utilization lies in linking small-diameter air lines to devices requiring a precise air supply, such as miniature pneumatic cylinders or instrumentation. The numerical designation refers directly to the size of the fitting, indicating compatibility with corresponding air line diameters.
The employment of standardized parts ensures efficient and leak-proof connections, contributing to the overall performance and reliability of pneumatic equipment. Historically, the adoption of standardized fitting sizes streamlined manufacturing processes and simplified maintenance procedures across various industries. The precision sizing allows for secure attachment, minimizing the risk of pressure loss and ensuring consistent operation of connected devices. Their use optimizes system functionality and reduces downtime, leading to increased productivity and cost savings.
