Yes, it's the fitting you've been looking for. Easily adapt a 3/4" barb / hose such as a factory intercooler pump, to a 10AN fitting.
These are commonly used by our customers for supercharger intercooler systems, but can have a lot of different uses for going heater hose to AN hose.
Sold each, **Machined finish only available currently.. Black will come back hopefully in the near future!
