How to choose the appropriate ORFS fitting size and specification in different hydraulic or pneumatic systems?

In hydraulic or pneumatic systems, choosing the right size and specification of ORFS fittings is the key to ensuring the normal operation and sealing performance of the system. First of all, the correct size selection directly affects the working efficiency and safety of the system. For hydraulic systems, the flow and pressure requirements of the fluid are the main factors that determine the size of ORFS fittings. Systems with larger flow rates require larger fittings to ensure that the fluid can flow smoothly without restriction. At the same time, the working pressure of the system also needs to be considered, especially in high-pressure hydraulic systems, the size of the fittings should match the inner diameter of the pipe to ensure that the seal does not leak and can withstand higher pressure.
When selecting ORFS fittings, the specification of the pipe is another important consideration. The inner diameter of the fittings should be consistent with the inner diameter of the pipe to ensure smooth flow of the fluid. If the fittings and pipes do not match, it may cause increased system resistance, which in turn affects system efficiency and accelerates equipment wear. When selecting, it is also necessary to confirm the thread size and sealing surface size of the ORFS connector to ensure that they can properly cooperate with other parts of the system.
Different hydraulic or pneumatic systems may need to consider different working environments. For high or low temperature working environments, the material selection of ORFS fittings also needs to meet the requirements to ensure that good sealing and durability can be maintained under extreme conditions. For example, in high temperature environments, the use of heat-resistant O-rings and stainless steel accessories can prevent seal failure and corrosion of accessories.
For pneumatic systems, the viscosity of the fluid and the compressed air characteristics of the system are also factors that need to be considered when selecting the size and specifications of ORFS accessories. Since compressed air in pneumatic systems is generally more susceptible to compression and changes than liquids, when selecting accessories, it should be ensured that it can withstand the pressure changes caused by gas compression, and the size of the accessories should be sufficient to ensure the stability of the air flow.
The sealing performance of ORFS accessories is critical, especially in high-pressure systems. The right size of the accessories can ensure that the O-ring fits the sealing surface perfectly, thereby preventing leakage. When selecting, you can refer to the sealing standards and relevant industry specifications of ORFS accessories to ensure that the selected accessories can meet the sealing requirements of the system.
