IA2 Series

ISO A couplers made to the ISO 7241:2023 Series A Standard Similar Faster NV Appearance

AKJia’s IA2 series is another ISO A, general-purpose, double shut-off, fluid transfer quick coupling available with a leak-free, high-flow poppet valve similar to our IA Series. it also complies with ISO 7241 Series A. They are used predominantly in Europe and are preferred worldwide for agricultural and forestry machinery, and body sizes of 1/2 and 3/4 also reach the additional dimension requirements covered in ISO 5675. The Appearance is similar to the Faster NV series, with sizes from 1/4″ to 1″.
