The unit is very nice, the brazing looks good and the straps are useful. However, it s NBSP (straight) not NPT for all of the 4 connections. NBPS is very hard to get a good seal to NPT, and also results is almost no thread grab. I am taking off 4 stars because of this so people are aware of the NBSP vs NPT issue. If you are installing in a location where some leaking is OK, this is the unit for you! Left is stainless nipple (with taper) right is unit (no taper).

I have ordered many things from Vevor and never had any issues until this order. This would be a quality piece if the fittings were machined correctly. The correct NPT fittings would not thread on to this heat exchanger. I contacted Vevor about the issue and they offered to refund about 1/3 of the price, I refused and they offered about 2/3, I refused and they refunded me 2/3 anyway. I told them that wasn't acceptable and they then offered to refund the remainder if I confirmed but they closed the chat and I wasn't able to confirm. I didn't have to confirm the first refund so I don't know why I had to confirm the second refund. I had to start another refund ticket and they promptly responded that they issued the refund but that hasn't happened yet.

WE NEVER RECEIVED THIS SHIPMENT. IS THIS A FRAUDULENT COMPANY? WE WANT OUR MONEY BACK.
