The main difference between ISO 7241-1 Series A and B lies in their sizes and applications. Series A is typically smaller, used in lighter-duty applications and has a lower pressure rating. Series B, on the other hand, is larger, used in heavy-duty applications and can handle higher pressures. I found this information from https://www.stucchiusa.com/iso-7241-1... - the differences are outlined in the section titled "What’s the Difference Between ISO 7241-1 Series A and ISO 7241-1 Series B?"

An ISO coupler, also known as ISO hydraulic coupler, is a device used to connect and disconnect hydraulic lines without causing fluid spillage or air inclusion in the system. It is widely used in various hydraulic applications such as in construction equipment, manufacturing machinery, and agricultural machinery to provide a fast and easy change of hydraulic tools or implements.
