1800psi rated:
Always make sure you are using the correct burst disc. Safety! This disc is used on many HPA bottles for the output pressure safety. This will also work on paintball CO2 bottles. If you are replacing a blown low pressure safety side disc on a HPA tank, you need to fix the regulator first. This disc only fails when the regulator has failed.
