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 :
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.
