💙 Blue Polypropylene IBC Cap Review

This thing turned out to be useless, should have female NPT threads but they are NOT NPT. Otherwise the product is good and fits in my pocket. Pretty cheap, for which I give three stars.

Good looking and well made product. However, the 2 plugs thread past the lip where the o-ring seals and will not allow the use of a 2" NPT fitting. For example 2" PVC for inlet connection.

I bought this to use as a diesel fuel storage tank in my shed. One of the holes will be schedule 80 PVC pipe for filling. The other hole is for the ventilation whistle. The threads in the 2" holes are pipe threads, not 55 gallon polymer tank threads.
