ISO International Standard

This document specifies the interface dimensions and basic performance requirements for two series of hydraulic quick-action couplings. Both series are in widespread use and have similar technological advantages:

—    Series A is used predominantly in Europe and is preferred worldwide for agricultural and forestry machinery. This document specifies additional requirements for Series A for use in the agricultural machinery applications given in ISO 5675.

—    Series B is used predominantly in North America and in the chemical industry.
