Here are a range of fitting suitable for IBC storage containers. We sell fittings for two IBC outlet sizes: 2 inch (60mm) and 4 inch (100mm) IBC Buttress threads. Respectively, these are also called S60 by 6mm and S100 by 8mm buttress threads. The 6mm and 8mm sizes denote the thread coarseness, measuring the thread from peak to peak.
We can also supply IBC fittings for different sized IBC outlets. New listings and fittings are being added to our online shop all the time. Please check the size of your IBC thread on your outlet before ordering. Our video will go through the different sized IBC outlets - Facebook - IBC Outlet Video
