“cootertwo”When the disc blew in my Yong Heng, I just installed 2 of the replacement discs, no more problem.


I would advise not doubling up the burst disc. It’s the same as using a nail to stop an elictrical fuse blowing. It may stop it tripping out but unless you know the cause, you run the risk of having a fire. In this case you risk an explosion. Using two disks will raise the burst pressure to over 10000 PSI, you might as well just use a stopper if you don’t want a safety device.

How are going to get “an explosion”?  Don’t all tanks have a burst valve on them?  If the valve is close on the tank you make burst a line, a connection on the compressor, or damage the compressor in some other way.  The volume of air in the compressor and lines is pretty small, once a burst happens it will pretty well be done with expending energy. 

I had problems with my Yong Heng burst disk failing in the 4000 to 4200 range.  The burst disk keeper ring on mine cracked and then the darn thing would not hold air at all.  I could not find a replacement of that ring.  I replace the burst valve with a bolt and o-ring….problem solved.  My tanks have 5000 psi burst disk on them.  I dont feel like I am in danger of an explosion and yes I have a healthy respect for the energy HPA has at these high pressures.  I also baby sit the compressor while it is running.
