Tire Hose Installation
• Attach air hoses to the hubcap and the inner and outer valve stems. The hose with the 180 ° fitting
attaches to the outer valve stem. Turn the valve stem swivel nut on the fitting until the rubber gasket just
makes contact with the valve stem, then turn the nut 1/2 turn more to ensure proper sealing. Now push
the hubcap end of the hose into the brass hose adapter fitting and turn the nut until the fitting is snug. For
final tightening, turn the check port stem and the nut at the same time using only your fingers. Do not use
any type of valve stem extensions. See Figure 24 and 26
• If installing on Super-Single wheel only one hose is required. See Figure 25

IMPORTANT: Make sure the hose(s) are not touching the tire rim. Contact between the hose and the rim
could damage the rim.
IMPORTANT: Make sure the tire hose(s) are not stretched so tightly that it puts a strain on the valve stem or
the hubcap fittings. Clock wheels if hoses are not aligned with the valve stems.
