Foam concentrate suction hose subjected to flushing water pressure must
be rated for 23 in (584.2mm) Hg vacuum and the maximum discharge pres-
sure of the fire pump (500 PSI [34 BAR] minimum). These hoses include
the hose from the outlet of the MDT II or MST to the foam pump inlet.
Recommended Components
❑ Hose: Aeroquip 2580 Series or equivalent reinforced hydraulic hose
❑ Fittings: Brass or stainless steel hose end crimp or reusable type
(Aeroquip 412 Series or equivalent)
A foam tank shut-off valve and drain valve should be provided in the foam
tank suction hose to allow strainer service, tank drainage and easier prim-
ing. These components are subject to the same material characteristics
and pressure ratings as stated above. When the In-line strainer/valve
assembly option is installed the shut-off valve is included. A separate valve
is not required.
Foam Concentrate Discharge Hose
The system installer must supply fittings and hoses from the foam pump
inject connection to the check valve/injector fitting inlet. All components
must be compatible with the foam concentrates being used in the system.
The foam pump discharge connection and the check valve injector fitting
connection port is 1/2” (13mm) NPT threads. Hoses and fittings of 1/2”
(13mm) inside minimum diameter rated at 500 PSI (34.5 BAR) working
pressure or maximum discharge pressure of the fire pump must be used.
Fittings and hoses must be compatible with all foam agents being used.
Recommended Components
❑ Hose: Aeroquip 2580-8 or equivalent reinforced hydraulic hose
❑ Fittings: Brass or stainless steel hose end crimp or reusable type
(Aeroquip 412-9-8 or equivalent)
Note: Although air brake tubing has been used for foam concentrate discharge
hose, it is not as flexible as the hydraulic hose and readily kinks during installa-
tion. Additionally, the air brake tubing may not meet NFPA 500 PSI (34 BAR) test
requirements.
