The port size has changed slightly over time, initially when we designed the CAT we sourced a manufacturer (in the USA) who made a good barb product, only issue was the bore was not large enough for the requirements we wanted in terms of flow. The fix was to re-drill these barbs out to the size we required.

Naturally this is a process which is not best use of time/resource so recently we have purchased a CNC lathe and are manufacturing our own barbs which we can make to our own specs and change them as required.

I understand your concerns but the bore size (smallest you have) is designed to work 100% efficiently with turbine sizes it is designed for.

However I am happy to ship you two CAT's with the same size bore in the barb FOC for your project to ensure you are totally happy - just PM me your details.
