The quick couplings have some important dimensions that according to the ISO standard, they can help the hydraulic coupling be interchangeable between different brands. it also can help the users to check the body size of the quick couplings from different brands or suppliers. And other dimensions would be needed to check when you have some special requirements for using the quick couplings. The ISO 7241 standard A series had listed the dimensional requirements for the necessary dimensions. The quick couplings fit the dimensions, they are interchangeable half-for-half among the different brands. The dimension d on the tip is usually helpful for us to check the body size if you have known the quick coupling is ISO A quick coupling. If you have an ISO A quick coupling but don’t know the body size, you can measure the diameter d. The Thread usually can be customized and we currently have NPT threads and BSPP threads for this series.
