B. Suggested Air Hose
The interior diameter (I.D.) of the hose is the most important factor, and any hose with the
correct I.D. and rated to withstand the expected air system pressures (500 PSIG burst
pressure) may be used.
We have found the most cost-effective hose is the push-on type hose, which is made by
Weatherhead. Their H101 or H201 general-purpose hose has an acceptable working
pressure. Also, Dayco, Parker and Aeroquip brands will suffice. All of these hoses come
in a variety of colors for color-coding the lines by purpose.
The other type of hose that is commonly used for air discharges is hydraulic hose.
Usually this is an SAE 100R1 type. Typically, hydraulic hose is not necessary on the air
discharge circuit, because the system air pressure will not exceed 150 psi. Also, the
hose and fittings for hydraulic hose are bulky and expensive.
Air brake hose may also be used, provided the inside diameters are correct:
.3
75” OD is .250” ID
.500” OD is .375” ID
.625” OD is .500” ID
.750” OD is .625” ID
C. Discharge Fittings
Suggested for 1” booster reel or 1” remote discharge:
Use 3/8” air hose
1- Water Check Valve (same size as discharge valve, suggest ball & cone style)
1-
½” Quarter Turn Ball Valve
You may also need to install an air pinch valve behind the panel for tuning this discharge.
Fittings per discharge:
4 - #6 JIC x 6 push-lock
2 -
#6 JIC x1/2” NPTM-90
1
– ¾” NPT-M x1/2”npt-f bushing
1 -
#6 JIC x ½”NPT-M
1 -
¾” NPT nipple
1-
½” Air Check Valve
If an electric solenoid valve is used for air instead of manual valve, use:
½” direct acting solenoid valve
Toggle switch SPST (suggest switch guard)
½”x 3/8” NPT bushing
#6x3/8” Female 37 JIC swivel to NPT-M adapter
Delete the following items:
#6JIC x 6 push-lock
1 - #
6 JIC x ½” NPT-M 90
