GeKa COUPLINGS

STANDARD
'GK' couplings are symmetric quick couplings designed for agricultural, gardening, construction and public service applications.

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.
APPLICATION
For agricultural, gardening, construction and public service applications.
WORKING PRESSURE
20 bar / 290 psi

TEMPERATURE
-30°C / -22°F up to 120°C / 248°F
Hose, coupling, assembly method and seal must be chosen in relation with the desired application and temperature range.
