You are right. On the description page, the UNBELIEVABLE diameter is nowhere to be found. It stated the diameter clearly on another brand I bought. The seller in question is unlike this one.
It is five eighths of an inch on The coolant bypass hose I used to connect my Dodge Caravan to it was made of this.
The depth of both sides is 5/8". A Dodge Caravan used this hose as a bypass hose for its coolant.
Using a four-inch measuring tape, I measured it from the outside to the outside of the hose. Item of great quality.

The method he used to bypass the heater core didn't work for me, so instead I bought this molded heater hose and connected it using brass fittings Since getting it about a month ago, I haven't had any leaks and it seems to be working well. The total cost of the parts was $30, and I would have been charged a couple hundred dollars if I had gone to the dealership. It was quite difficult to disconnect the heater core hoses from the engine block since the heater core was more than 20 years old. We had to work on that a little while and refine it a lot. I am very happy with the repair and am about 5,000 thousand miles from reaching 100k miles.
The ss hose I needed for my ls swap was a u bend. My heating system does not have a u bend, so I had to get one. It's a fairly cheap hose, and people are saying they have no issues with it. The hose itself is the same size on both ends, so that shouldn't be a problem. Both the inlet and outlet of the heater core are different sizes on the water pump. Getting on the larger of the 2 was a bit of a problem. We hit the one end with brake cleaner to soften it up for a few minutes and then it went on smoothly. In this case, there is a better hose that is the correct size on both ends and exactly what this application requires. The price was not as cheap, but I think if I were to do it again, I would not waste the time and hassle and just pay the extra money.
It was a pleasure working on my LS swap. The heater core will be deleted.
The truck did not come with a heater valve and I figured Dodge had it setup that way for a good reason. I used this to loop my heater hoses together. Many say you would need a flow valve, but this was my solution. Consequently, I purchased this product, along with a couple 5/8 hose connectors and some SAE 12 clamps. The truck is no longer mysteriously losing coolant now that we have installed it.
I found this material to be helpful. As the heater I have going round the block, I’ve used this hose to bypass it. The one thing to consider when using a bypass hose is to employ any kind of flow control to reduce the flow to a minimum. Otherwise, full hot water will flow back to the engine via the bypass hose bypassing the thermostat, which will increase engine revs. To reduce flow by 5%, I used an inline flow control system (DIY). There is no problem with the engine, it works fine.
In spite of the fact that I live in Florida and the vehicle has heated seats, it was easy to bypass the heater because the blend doors were stuck and required removing the entire dashboard. The AC is now blowing cold air. A simple installation process takes only a few minutes.
This worked perfectly on my 12v Cummins to block off the heater lines to my heater core while I flushed it out.
My 1985 Isuzu Pup was in the middle of a timing belt replacement when I discovered that the bypass hose was extremely cracked. A replacement was shipped overnight, and it was a waste of money as you see from the picture above. It seems that cracks in the bend go through the outer layer of the hose as well. I am waiting for a replacement and am crossing my fingers that it will function as intended.
