Hi heater hose is a no no. It will do for a patch job but thats it. Oil resistant hose is the way to go, something like transmission cooler hose. Earls performance in sliverwater is a hose specialist with quality products but it comes at a price.

Very bad idea to use heater hose, its not design for the pressure or the temprature of oil, its also not chemicaly resistant to oils so it will rot and split probably costing you a new set of bearings and machine work.

Dunlop - Gamlock is a damm good hose to use for oil and isnt very expencive at all, as the guys already said all your good hydro shops will have it

I use push-loc oil hose for the remote oil filter on my V8 mopar.

yea drop into any hydrolic store and see whats avaliable for your application

Heater hose isn't rated for oil,
I'd suggest swing down to the nearest Couplers, Enzed or the like and pick up some Braided hose for the job...

Hey giys any ideas on what you can use for engine oil cooler hose?
Keep in mind the temps will be around 90-100C and pressure around 60-70psi. Now Im thinking standard heater hose should be ok, as I used to run a Permacool engine oil cooler kit and had no problems. Im not sure however what hose they run in their kits. Maybe I need to run EFI fuel hose to cope with oil ...your thoughts or ideas and where I can get it from. I need 5/8 or 3/4" internal diameter hose for this application.
