Hello All
All is well with you.
I got a Failured rubber(NBR) O-ring as soon as machine operated.
The manchine has been under 1.5bar and athmosphere temperature and it was not contacted any steam or water.
It had only some lubricant oil
I found out rubber o-ring had transverse failure mode as soon as dis-assembled manchine.
You guys can see the failure mode O-ring as below photo.
and I cut the failure part of O-ring
the surface of O-ring is very smooth but there are some porosity?
Could you please advise me the casue of failure and other reason?
