What is the Amerex 07292?
Amerex 07292 is the nitrogen hose assembly listed as item 5 in Amerex Parts Book 27277 Rev D, printed page 19, for the 300/350 lb wheeled extinguishers, models 491 and 493. It is the high-pressure gas supply hose that connects the 55 cu. ft. nitrogen cylinder valve to the agent cylinder, and Owner's Service Manual PN 05614 sets its hydrostatic test pressure at 3000 psi on the 12-year retest — ten times the 300 psi required of the discharge hose. The manual's troubleshooting guide instructs technicians to replace the hose with this same part number, PN 07292, whenever it is found cut, cracked or abraded.
