Garden hose quick couplings, 40 mm clamp width

Garden hose couplings (often also called "GEKA coupling") made of brass or stainless steel are used to couple water hoses quickly and economically. They are symmetrical, non-shut-off couplings with 40 mm claw distance (Caution: Risk of getting mixed up with the compressor coupling with 42 mm claw distance!), which are coupled by twisting the claws with each other. A differentiation is not made between plug and sleeve. As the coupling has no shut-off function, it must be ensured that before coupling the line has no pressure. The danger of decoupling under pressure is reduced with a safety coupling: when decoupling first the seal is turned back (pressure relief) and then the claws are twisted against each other.
