The Development Story Behind CPP’s New All-Plastic 2" Threaded IBC Vent
If you’ve ever specified, filled, stored, or shipped an IBC, you’ll know the vent is one of those parts that gets noticed only when it doesn’t do its job. Too tight and the container can pull a vacuum as product discharges. Too loose and you can end up with nuisance leakage, odour issues, or a vent that “breathes” when it shouldn’t. And when you’re dealing with aggressive liquids, the vent’s internals can become the weak link long before the IBC itself.
That’s exactly why we set out to develop a new CPP all-plastic 2" threaded IBC vent: a purpose-built, robust, repeatable design that solves common real-world vent problems—without relying on metal springs or mixed-material assemblies.
This is the story of how it came together. https://cpp.parts/blogs/news/cpp-s-new-all-plastic-ibc-vent
