ISO A Quick Couplings

ISO A Quick Couplings, also known as ISO 7241-1 Series A Hydraulic Quick Disconnects, are industry-standard couplers designed for reliable and leak-free hydraulic connections. These couplings are widely used in agriculture, construction, and industrial machinery, providing a secure and efficient way to connect and disconnect hydraulic lines.

Once you have confirmed that the quick coupling you need is an ISO A quick coupling, you can find the quick connector you want by further subdividing it into material, body size and thread. The material carbon steel, usually used for the hydraulic applications, the working pressure usually 200 bar to 350 bar, and for the fluid of hydraulic oil. And the stainless steel usually for the water or chemical fluid etc. The pressue usually 1000 PSI. The working pressure related to the material and the size. Then the body size is usually related about the flow rate. And the treads usually related for the connecting to the hose, and based your country thread standard. For example, in America, it usually NPT or SAE etc. In Europe, it usually BSP or metric thread. In Australia,it can be both NPT or BSP. Contact us if you need help.
