How to stop hoses bonding to pipework.

[mriley]

I'm replacing the hoses on my cooling system. Anybody know the best thing to use to stop hoses sticking to pipework when clamped - I had a struggle getting some off that had become bonded to the pipes. Thought about Vaseline, but it might not survive the heat. I'm also wary of using anything that might degrade the hose material.

The best hoses are those made from a silicon material, they do not fuse onto the pipes and last and last the old rubber ones do fuse and also become hard and crack up. Not sure what engine you have but Mermaid and Sabre use nothing else.

Don't forget vaseline is "petroleum jelly" not sure how flamable is might be?
Some telephone cables contain this material and it is inadvisable to use them indoors.

silicon grease'll stand the heat ok I would think - plumbers merchant should keep it.

Cant tell you how to stop them bonding, but a liberal dose of wd40 makes most of them easy to remove.
If you are renewing them just cut them along the bit thats bonded saves lots of skinned knuckles & time

I presume you need reinforced hose to avoid them collapsing under suction. This stuff is impossible to remove once it's been in place for a while as it shrinks due to the heat of the water.
I made up hose tails for mine using standard copper plumbing tube. The tube is fitted into the reinforced hose and clamped in the normal way. At the other end I used a short length of standard car heater hose between the copper and the fitting that the hose goes on to. The heater hose is too short to collapse and goes on and off the fitting with no probelms at all, even after a couple of years!
