ISO 7241 Series B Standard specifies the interface dimensions, the necessary dimensions must meet the request from the ISO 7241 Series B standard, so the ISO B quick couplings will be interchangeable among different suppliers and brands. The Dimension D on tip half can help us to confirm the body size if you have known they are ISO B Quick Couplings, measure the diameter of the male tip half. The length dimensions are usually not necessary for common use. Need to check if your application will request some special requirements. Actually, the appearance is not so important but lots of users don’t know if the interchangeable quick coupling can work perfectly to replace the current coupler, so they usually wanna find a 100% same or similar replacement part. As a manufacturer, we have some different appearances as customers’ requirements.
