Any ideas on how to stop hoses from kinking?



I've recently assisted with replacing some coolant hoses on a 912 

engine. The new hoses aren't as stiff as the old ones, and have a 

tendency to kink slightly in a couple spots, which would lead to 

reduced internal diameter.



Some options involve changin the whole setup: find stiffer hoses, add 

angled joints, or look for pre-formed auto hoses that better match 

the needed shapes.



Tying the hoses down in certain places distributed bending stresses 

and therefore reduces the tendency for the hoses to kink at a certain 

spot. Another solution I'm experimenting with is to wrap the hose in 

the critical spot with sheet aluminum, which is then compressed with 

a tie wrap, in an attempt to force the hose to "stay round", and/or 

not to bend as much at that point along the hose.

how about a light weight spring inside, just like a lower radiator hose on a 

car!

Hi Peter & all,



The best I've found is to get a suitable spring wound by a spring 

manufacturer to snugly fit the O.D. of the pipe - not too hard to do 

yourself with some 2mm diameter spring steel wire on a former (broom stick 

handle ? )



Cheers, Charles Davis
