At present, IBC manufacturers in China basically use stainless steel wrench type quick couplings for quick connection and quick discharge.
The quick connector in the picture is an F-type male quick connector for exhaust. The DC-type female quick connector in the picture is combined with the male quick connector A. It is used for injection. The DC quick connector acts as a Protection and dustproof function. In other countries, lug-type quick-connects are mostly used. There are threads in the dust cover. It has advantages and disadvantages with wrench-type quick-connects. The wrench-type quick-connect is faster than the lug-type quick-connect on the quick opening and closing, but the lug-type is faster. Because the connection is threaded, it is still good in terms of safety. If the wrench type quick connector is easy to detach under special circumstances, such as an earthquake, the solution can be solved by adding a secondary locking pin.
