What is the Amerex 09895?
Amerex 09895 is the complete valve assembly with downtube for the Amerex 333 (50 lb) and 334 (100 lb) carbon dioxide wheeled extinguishers, item 16 on Parts Book printed page 21 (PDF page 23). The wheeled catalog specifies a DOT/TC cylinder with a quick-opening brass “T” handle valve; pulling the “T” handle opens the cylinder valve so CO2 rises through the downtube. The Parts Book diagram groups the valve lever, safety disc, valve stem, spring, retainer, downtube and lock wire seal under this assembly. Service calls for a new valve stem with the O-ring lubricated with V-711. Amerex requires genuine factory parts to protect the UL listing and keep the warranty in effect.
