The basis for this RS - camlock coupling variant is the camlock coupling as per EN14420-7. This variant is equipped with an additional spring-loaded latch on the female section that engages with a prefabricated grove on the male section behind the coupling body. This way, an unintentional opening of the hand lever under pressure – that is, an uncontrolled decoupling – is avoided.
Via DIN2828, the standardised coupling system originated from the American “military specification” MIL-C, which is still widely used today. With this coupling system there is also a male and a female section for which there are both protective caps and threaded plugs. EN14420-7 standardises the nominal widths DN20/3/4“ – DN100/4“. Each male and female section is available in many different connection variants: Female thread, male thread, barb fittings for clamp integration with clamps, hose fitting for safety clamps as per EN14420-2, weld ends and flanged connections. The operating temperature is defined from -20 °C to +65 °C.
When the hose line is fully loaded and being strongly bent, the additional latch also provides sufficient safety against unwanted decoupling.*
Despite of its additional feature, the coupling is compatible with the customary camlock couplings as per EN14420-7, i.e. it can be coupled crosswise.**
