Not sure what you are asking; however, I have two 5g Blitz around 10-15
yrs old and a 5g Rubber Maid also 10-15 yrs old.
English measurements did not make sense so got out the metric ruler.
Both brands have about 1 thread per 4.5mm or around 5 threads per inch.
The RubberM can opening is 43mm wide and it's spout is loose on the
Blitz. The Blitz can opening is 42mm wide and it's spout is too small
to fit on the RubberM. The Blitz "can" has 2 threads, the Rubb "can"
has 4 threads. Both spouts have 4 threads. They are not
interchangeable between brands.
The Blitz does not have a gasket. It uses a double cone shaped jam seal
for under and over the spout, nut, and can. The Rubb has a gasket
between spout and nut but a flat compression seal between spout and can.
The Rubb system appears to be somewhat better than the Blitz system.
My Blitz's would need the coarse caps.
