A Guide to Choosing an IBC Tank and Outlet Connection

Intermediate Bulk Containers are widely used for storing and transferring liquids in industrial, agricultural, chemical and food-related applications. The container itself is important, but the outlet connection is just as important when you need to connect a hose, pump, valve or dispensing system.
Start with the application
Choose an IBC for the liquid, transport method, storage environment and handling process involved. Check the tank, cage, pallet, valve and closure specifications supplied by the IBC manufacturer, particularly for regulated or hazardous products.
Identify the outlet before buying an adaptor
IBC outlets that look similar can use very different threads. Common connections found in the CPP® range include S60X6, S100X8, 2″ NPS and 2″ Camlock. Older and specialist valves can use other formats such as S75X6, S92X4, M80X3 or DIN-style connections.
Do not identify an outlet by tank brand alone. Reconditioned IBCs are often fitted with replacement valves, and the valve currently installed may not match the original tank specification.
Choose the final connection you need
Once the IBC outlet is known, decide what the system needs on the other side: Camlock, BSPP, BSPT, NPT, hose tail, garden hose, valve or another IBC connection. CPP® manufactures fixed and swivel adaptors, reducers and conversion fittings to cover many of these combinations.
Think about venting as well as discharge
An IBC being emptied needs air to replace the liquid leaving the container. An unsuitable or restricted vent can allow negative pressure to build and pull the bottle walls inward. The vent should be selected for the expected discharge rate and the IBC manufacturer’s limits.
Remember that an IBC is not a pressure vessel
Adaptor pressure ratings do not authorise pressurising an IBC. Always follow the tank and valve manufacturer’s operating limits and treat the complete system according to its lowest-rated component.
