What is the Amerex 03501?
Amerex 03501 is the 3/4 in. x 50 ft. discharge Hose Assembly used on the 488 and 490 125 lb stored-pressure wheeled extinguishers (Parts Book p.16, item 22) and the 450/452 nitrogen-cylinder-operated 125 lb wheeled family (p.18). Amerex's owner's manual specifies the hose runs the full 50 ft to the nozzle and gives a coiling procedure — alternating reverse and front loops between the carriage's hose support brackets — so it uncoils without kinking during a fire. It ships without the hose/nozzle gasket, which is a separate part, and Amerex requires genuine parts to protect the UL listing and warranty.

Amerex 03501 questions
What does the Amerex 03501 hose assembly fit?
The 488 and 490 125 lb wheeled dry chemical extinguishers (Parts Book p.16) and the 450 and 452 nitrogen-cylinder wheeled units (Parts Book p.18).
How long is the Amerex 03501 hose?
3/4 in. x 50 ft., matching the 50 ft. hose length specified in the 488/490 owner's manual.
Does the 03501 hose assembly include the gasket?
No. The Parts Book lists it as "without Gasket"; the hose/nozzle gasket (03877-P) is a separate part.
How should the hose be coiled onto the carriage?
Amerex's manual instructs alternating loops — first regular, then reverse, then regular — for six full loops between the carriage's side and top hose-support brackets so it feeds out without kinking.
Is the Amerex 03501 a genuine Amerex part?
Yes. Amerex's Parts Book notice states genuine parts are required to protect the UL listing and keep the warranty in effect.
Does the discharge hose need hydrostatic testing?
Yes. Amerex's 488/490 owner's manual specifies the discharge hose be hydrostatically tested to 300 psi (2068 kPa) every twelve years.
