Empire Paintball Compressed Air Tank / Co2 Tank Regulator Unified Burst Disc - Nickel (GG05-09)

A burst disc, also known as a rupture disc, is a safety device that protects systems from overpressure or vacuum damage. It's a non-reclosing, fail-safe pressure relief device that's used in liquid and gaseous systems.

Burst discs are reliable because they don't have any moving parts. They are also relatively simple to install, operate, and maintain.
