What is the Amerex 04523?
Amerex 04523 is the 1/4 SS pipe nipple (Amerex part 04523, item 29) on the 110 cu. ft. wheeled parts page for models 467, 469, 470 and 472. The Parts Book lists the same part number at item 27 on the Argon page for the 680R and 681R Class D wheeled units, printed there as the 1/4” SS Pipe Nipple. Those are the only two pages that carry it: it is not listed on the 23 cu. ft. or 55 cu. ft. wheeled pages, nor on the CO2 wheeled page. The Parts Book notice states Amerex replacement parts must be used to protect the UL listing and keep the warranty in effect.
