Query: Strongest bulkhead fitting available.

I don't always use these Banjo fittings for every job because they are much higher in price but with a wall thickness of approximately 11 mm at the thinnest point (the jam nut) - these are super strong. I've never seen one break in 20 years of industrial use. If you need strength this is the best bulkhead fitting. Period. Also note that there are female threads on both sides of the fitting which the cheaper ones don't have.
