The N series is the only one that is produced also with the ball shut-off system.These couplings are often used on tractors and other agricultural
equipment: for this reason N series is also known like “AGRICULTURAL” series.This terminology is not correct because this type of couplings is
suitable also for many other hydraulic applications in several productive fields.
