epdm hose

[ppea]

I replace a suction hose from my hydraulic pump on my tractor and after that i saw it's a epdm multipurpose hose and it's not compatible with oil. How long will it take to start degrading and cause problems ?

You need to look for a replacement and not leave it until you have problems as it will deteriorate and could cause problems with your hydraulics. It will start to get gummy where the oil runs.

It's all the time oil inside hose and it's 90cm long.I thing maybe last one year or two.

EPDM will not last long . You need a Nitrile hose

It won't last long, but the inside of the hose could start shedding material and end up clogging or damaging hydraulic components.
Change it as soon as possible!

I check and the previous hose was DIN 73411 that means it was epdm too.I thing it was on tractor a few years and has no sign of wear in interior.

EPDM is more weather resistant that nitrile and repels water better but depending on type of EPDM compound it may or may not be hydraulic oil resistant.

DIN 73411 is meant for antifreeze and is intended for radiator coolant hose.

Well, it's your tractor.
