Material
High-pressure hose couplings are typically made of metals like stainless steel and carbon steel. Selecting the right material ensures good corrosion resistance and strength, enabling the couplings to perform well in various working conditions.
Sealing
The sealing of the joint is crucial as it directly impacts the safety and reliability of the system. Opt for couplings with excellent sealing performance to guarantee the smooth transfer of fluids or gases. Additionally, consider the pressure-bearing capacity and service life of the joint to ensure it can withstand the required pressure and last for a long time.
Beyond material, there are other important aspects to think about:
Diameter
The diameter of the coupling must match that of the hose for a secure and tight connection. Common diameters include 6mm, 8mm, 10mm, etc., and custom sizes are also available.
Thread Size
For threaded connectors, the thread size should be compatible with the hose to achieve a reliable connection. Common thread standards are ISO, Metric, and Imperial. ISO threads, such as M6, M8, M10, etc., are particularly common.
Special Functions
High-pressure hose joints may have special features. Swivel joints, for example, allow the hose to rotate during use, reducing distortion and damage. Protective sleeves offer extra protection, making the joint more durable and corrosion – resistant.
