IBC Adapters…….Fitting Information

All of our adapters fit the most common type of UK/European IBC thread on the outlet pipe (after the valve), which are known by any of the following names/details :

  • S60x6 Thread

  • 60mm - Buttress/Coarse Thread

  • Schutz Type IBC (Buttress/Coarse thread - NOT Fine Thread - See Below)

  • DIN61 or DIN 6131 Thread

  • 2" or 50mm with a coarse thread. (This is easily confusing, if you measure thread peak to thread peak then it is 2.5" or 60mm. If you were to measure the ID or bore (Internal Diameter) it is 48 - 50mm, which is where the 2" comes from. They are both the same IBC outlet, the common type, just measured differently.

The Outlet/IBC thread has the following dimensions

  • Thread Diameter =60mm (D1)

  • Thread Pitch = 4mm (P1)

  • Thread Root = 54mm

  • Threads on IBC outlet = 2 - 3 (There are 4 threads per inch, but outlet pipe is less than 1", hence 2 - 3 threads)

Which will look like the picture below

Other Types of IBC Fittings

The only other type you are likely to encounter is a larger size known as either S80 (3" Bore) or S100 (4" bore), OR where a CAM LOCK fitting is either present (no threads), or has been removed and there is a FINE pitch thread instead, which is often found on Schutz Brand IBC's with the following dimensions (2" IBC bore, 58mm Edge to Edge thread, but LOTS of thread turns per inch (5 - 7), think of a plumbers pipe thread, rather than the 2 - 3 of a buttress thread).  





BEWARE when fitting the Heavy Duty Adapters

To install the Heavy Duty IBC Adapter:


The picture is the result of an incorrect installation. This is NOT covered by warranty, as it caused by incorrect installation, by over tightening. Don’t make this mistake


Ensure the white seal or Viton seal is present, using ONE of your hands, and holding the base of the adapter (as in the picture), not the fitting (hose tail, equal tee, etc). When you feel contact with the seal, very lightly “snug” the adapter against the seal STOP.

DO NOT KEEP TURNING. The adapter does not need to be super tight to prevent a leak, just “snug” against the IBC thread/Seal.

DO NOT USE TWO HANDS, DO NOT USE ANY TOOLS. One hand is enough to get a good seal. If the fitting after the base is out of line (such as a tee piece, then note the position, take the adapter off, and turn the fitting back appropriately, then refit the adapter as above. Do not try and line up your fittings by turning past the point that the adapter seal is snug. You will break the threads. This is not a fault of the adapter
