Just looking on the internet I ran across this: 3/4" BSP x 7/8 hose barb stainless fitting. Here is the part # Kegland Stainless Barb --KL06668 price was about $5. Sounds like it was made for the brewing industry. Supposed to fit 7/8" ID tubing.


Just so you know...........This is British thread which is different than NPT. It is so close and may work?

NPT and BSP threads are not interchangeable due to the differences in thread forms. NPT threads are pointed in the peaks and valleys, where BSPs are rounded. Most notably, the NPT thread angle is 60 degrees versus the BSP 55-degree angle.

Though it has been tried, problems always arise when trying to thread a NPT male form into a BSPP female form. The dissimilar pitch will allow a misalignment of the threads, which causes leakage of fluid and even catastrophic failure under pressure.
