Technical specifications of pneumatic fittings

The technical specifications of pneumatic fittings primarily include port specifications, operating pressure, applicable temperature range, material composition, sealing performance, and service life. These parameters directly influence the connection quality and the operational stability of the pneumatic system. Specific technical requirements vary depending on the type of fitting, its structural design, and the intended application environment.

Port specifications are a crucial aspect of pneumatic fittings, typically encompassing thread size, tubing outer diameter, and connection type. Common tubing sizes include 4mm, 6mm, 8mm, 10mm, and 12mm; fittings must be matched with the corresponding tubing size. Common thread specifications include M5, G1/8, G1/4, G3/8, and G1/2; selecting the correct thread size ensures a secure installation and unobstructed airflow.

Operating pressure and temperature resistance are also vital technical indicators. Standard pneumatic fittings generally meet the pressure requirements of typical industrial pneumatic circuits, while certain high-performance models can withstand higher-pressure environments. Furthermore, material selection must align with the operating temperature range to ensure stable performance in high-temperature, low-temperature, or specialized environments.

Sealing performance, tensile strength, and corrosion resistance are other key parameters. An effective sealing design minimizes compressed air leakage and enhances energy efficiency; high mechanical strength ensures long-term connection stability; and corrosion-resistant materials extend the product's service life. When selecting pneumatic fittings, one should comprehensively consider equipment requirements, the operating environment, and pneumatic circuit parameters to ensure the safe and reliable operation of the pneumatic system.
