05240 AMEREX ORING FOR WHEELED UNITS

Description

The Amerex 05240 O-Ring is a replacement collar seal used on wheeled Amerex dry chemical and other fire extinguishers equipped with brass valve assemblies. It fits around the valve flange (valve collar) to maintain a tight seal between the valve and agent cylinder, preventing loss of agent or pressure leaks. Designed to match Amerex’s factory tolerances, it helps restore extinguisher integrity during maintenance or refurbishment of wheeled units.
