What is the Amerex 23811?
Amerex 23811 is the valve stem assembly for Amerex's Halotron I stored-pressure wheeled extinguishers, listed as item 17 on Parts Book page 24 (65 lb. B673) and item 19 on page 25 (150 lb. B674, B675) — the same part number serves all three models. At every six-year complete maintenance the service manual has the old stem assembly and the collar o-ring removed and discarded, then a new GREEN SEAL stem assembly installed after lightly lubricating its valve stem o-ring and valve stem seal with V-711. Per the Parts Book notice, genuine Amerex replacement parts protect the UL listing and keep the warranty in effect.
