Of the hoses they sell on that site, it looks like you picked the
better option.

I like the 212-degree "plus" heat rating. The other hose that go2 is
peddling is only rated to 190. If you develop an overheat, the last
thing you need is for a hose to crap out as well. In a pressurized
system, you can achieve temps well above 212-degrees with a liquid
coolant.

Is this particular, wire reinforced product flexible enough for your
specific application?
