趣购彩两者使用的场合不同，液压接头适用于高压场合，而气动接头适用于低压场合。

The two are used in different occasions. The hydraulic connector is suitable for high-pressure occasions, while the pneumatic connector is suitable for low-pressure occasions.

两者的螺纹连接也有很大的不同，气动接头大多使用的是PT牙、NPT牙、G螺纹。液压接头使用的螺纹则很广泛，有公制螺纹、英制、美制螺纹等。

Most of the pneumatic and g-thread connections are very different. The threads of hydraulic joints are widely used, including metric thread, British thread, American thread and so on.

两者在材质上也有区别，气动接头使用塑料的很多，液压接头大多使用碳钢或不锈钢等。而且气动接头的厚度和质量要求也没有液压接头的高。

There are also differences in material between the two. Many pneumatic joints use plastic, and most hydraulic joints use carbon steel or stainless steel. Moreover, the thickness and quality requirements of pneumatic joints are not as high as those of hydraulic joints.

趣购彩两者的价钱也有很大的差距，液压接头要比气动接头贵上很多。

There is also a big difference in the price between the two. The hydraulic connector is much more expensive than the pneumatic connector.

液压管接头的耐压很高，常用的有16MPa, 25MPa, 35MPa几个级别。而气动管路的压力一般是0.8MPa。

趣购彩The pressure resistance of hydraulic pipe joints is very high. The commonly used ones are 16MPa, 25MPa and 35MPa. The pressure of pneumatic pipeline is generally 0.8MPa.
