Each Geka fitting consists of two coupling pieces which can be combined as desired. Hose coupling 1 inch means that a 1 inch hose with 25 mm inner diameter fits to the nozzle of the Geka coupling.
To connect it to an IBC, you need an adapter from IBC-thread to Geka (bayonet) ibc-geka or ibc-geka-profi and a matching part to connect the hose to.
A standard coupling seals by turning the bayonet connectors against each other, but this connection will leak out under low pressure - it is not suitable for the suction hose.
To connect the suction side of a pump, we recommend the suction coupling. After the bayonet has latched, the latch can be tightened by a knurled-head bolt .
Thus, first the coupling can not unscrew itself and secondly it remains permanently resitant against low and high pressure.
We recommend to order an additional seal geka-sk-d as the standard Geka sealings do not fit for suction couplings.
