This is a replacement 3000psi burst disk for KegLand 2.6kg or 6.0kg CO2 Cylinders.

If you leave a cylinder in a hot car or hot garage the temperatures are likely to exceed safe working pressures for the cylinder itself.  If you are in this position you might hear the burst disk blow and all the of the remaining gas in the cylinder escape. It is important to make sure a cylinder is in a big enough space for the remaining CO2 to disperse into the atmosphere and not fill a small room. Storing cylinders in a cool environment will prevent this rare incident ever occurring.

Simply unscrew the old one with a shifter and place the new burst disc in its place.
