OPERATION
‘GK’ couplings are connected by pushing and rotating the two couplings together. The claw distance is a 40 mm and therefore interchangeable between all dimensions from DN 10 to DN 38. 'GK' couplings are not interchangeable with Express couplings complying with NF E 29.573 and European air couplings complying with DIN 3489.
N.B.: Due to the wide range of ‘GK’-type seals, ‘GK’ couplings can not always be connected with those of other anufacturers.
