Wholesale PricingThe Amerex 05564-P001 Hose & Horn Assembly is the OEM replacement fire extinguisher hose and nozzle unit for Amerex 5 lb. through 20 lb. ABC dry chemical fire extinguishers. The 3/8" (.191) specification refers to the internal bore diameter and thread pitch, ensuring a leak-free, pressure-rated connection to the Amerex aluminum or brass valve body. This is a direct fire extinguisher hose replacement for the original factory-installed assembly, maintaining the UL listed rating of the extinguisher.
A damaged or degraded hose is one of the most common fire extinguisher inspection deficiencies found during annual and semi-annual reviews. Cracks in the rubber jacket, loose crimp fittings, or a blocked discharge horn can prevent the full agent charge from reaching the fire — making the fire extinguisher hose replacement a critical safety repair. Genuine Amerex fire extinguisher hoses are pressure-tested to exceed the rated working pressure of the cylinder, providing the reliability that fire extinguisher parts and supplies professionals demand.
This assembly includes both the flexible rubber hose and the discharge horn, making it a complete replacement unit for your fire extinguisher nozzle and hose system. It is compatible with the full range of 5-20 lb. Amerex ABC dry chemical fire extinguisher models and is a staple item on any fire equipment catalog for Amerex service shops.

When to Replace the Hose Assembly
Under NFPA 10, fire extinguisher hoses must be replaced if any of the following conditions are found during inspection: cracks or cuts in the rubber jacket, blocked or deformed discharge horn, loose or corroded crimp fittings, or any evidence of agent contamination inside the hose. A failed hose is an immediate red-tag deficiency and the unit must be removed from service.
Installation Protocol
When installing the 05564 fire extinguisher hose replacement, ensure the valve body threads are clean and free of old Teflon tape or sealant debris. Thread the hose assembly hand-tight, then torque to the manufacturer specification. Do not over-tighten — the brass threads on the valve body can be damaged. After installation, pressure-test the connection before returning the unit to service.
Discharge Horn Inspection
The discharge horn must be free of blockage and physically intact. A cracked or deformed fire extinguisher with hard horn will produce an irregular discharge pattern that may not effectively suppress the fire. Replace the entire 05564 assembly if horn damage is present rather than attempting to repair the horn individually.
Is this compatible with all Amerex ABC models?
The 05564 is specifically rated for Amerex 5-20 lb. ABC dry chemical extinguishers with the 3/8" (.191) thread specification. Always verify your model's fire extinguisher parts list before ordering to confirm the correct hose assembly for your specific unit.
Can I use a generic fire extinguisher hose clamp instead of replacing the full assembly?
No. Using non-OEM repair methods on the discharge path voids the UL listing and creates a liability risk. The entire fire extinguisher hoses assembly must be replaced with a genuine Amerex 05564 to maintain factory-certified performance and compliance with NFPA 10.
Does this include the nozzle o-ring?
The 05564 assembly includes all components required for a complete fire extinguisher hose replacement. If a separate hose nozzle o-ring is needed for other maintenance tasks, it should be sourced from the Amerex fire extinguisher parts catalog as a separate line item.
