🔵 FlexFab - 1in ID x 10ft 5526 Blue Silicone Heater Hose: High Temperature Radiator Coolant Solution Review

Bought these hoses to replace the water hoses on my Mercruiser v8. They are tough but very flexible. One of the best high temp hoses I've found.

Used as drain hose (replaces rubber hose) for marine air conditioning drain. No problems with algae and dirt sticking like rubber. Very happy with the end result!

This hose looks good but the silicone doesn't seal the pipe like a rubber hose. I've used it with expensive all-silicone hose clamps and almost every fitting has leaked. I've gone around and tightened all the clamps to the max and even double clamped some and I still have a few slow drips even after several heating cycles. Now I plan to open up the engine compartment again and replace them with Gates rubber hoses. So this purchase will not only spend my money on the hose, but about a day's work
