Options / Ideas for removing rear heater.

Hi everyone, looking for some advice please …

I hope my reference sketch makes sense.

My 97 Thomas has rear heat which I am removing and no longer want. Question is. I would like to plug the T valves like in option B. That would still complete the circuit/flow, but I wonder if that would force or put to much pressure in the driver heater.

If I looped a patch hose back around in a U shape like in option A, I wonder if that bypass would act as path of least resistance, and less/not-enough fluid would pass through the actual driver radiator. It kind of seems like it would be that way in the original setup anyhow…

So the main question is any reason to NOT just plug ends like in Option B?

Secondly since that’s what I am leaning toward doing ….. Any ideas on how to plug those ends. I don’t want to sweat copper caps on them. The inner diameter of the hose is 1-inch.

There is a rubber cap at ... ge372.html I am thinking of using something like this (it’s at the bottom of the page) You think this would be durable enough? Or can you recommend something else?

9$ a pop seems high, called a few parts stores and seems they only have up to 3/4” caps.

Thank you all!
