兩者使用的場合不同，液壓接頭適用于高壓場合，而氣動接頭適用于低壓場合。
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.
兩者的螺紋連接也有很大的不同，氣動接頭大多使用的是PT牙、NPT牙、G螺紋。液壓接頭使用的螺紋則很廣泛，有公制螺紋、英制、美制螺紋等。
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.
兩者在材質上也有區(qū)別，氣動接頭使用塑料的很多，液壓接頭大多使用碳鋼或不銹鋼等。而且氣動接頭的厚度和質量要求也沒有液壓接頭的高。
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.
兩者的價錢也有很大的差距，液壓接頭要比氣動接頭貴上很多。
There is also a big difference in the price between the two. The hydraulic connector is much more expensive than the pneumatic connector.
液壓管接頭的耐壓很高，常用的有16MPa, 25MPa, 35MPa幾個級別。而氣動管路的壓力一般是0.8MPa。
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.
