The Amerex A3787 is a safety disc (rupture disc) assembly used in Amerex wheeled stored-pressure dry chemical fire extinguishers to protect the agent cylinder from overpressure. If cylinder pressure ever rises beyond the safe operating range, the disc ruptures in a controlled way to vent that pressure before the cylinder itself can be damaged.

- Used in the 125/150 lb. wheeled dry chemical extinguishers (Models 450 ABC, 452 PK) and 300/350 lb. wheeled units (Models 491 ABC, 493 PK)
- Mounted in the agent cylinder cap assembly, alongside the cap gasket and nitrogen tube/downtube assemblies
