The document discusses how to properly specify parts for Aperia's Halo tire inflation system. It explains that Aperia uses smart part numbers to identify applications. It stresses the importance of providing vehicle, axle, wheel, and hub details on the order spec form in order to select the correct kit, including brackets, hoses, and stand-offs that will fit the application. Contact information is provided for parts and support.

Aperia uses “smart part numbers”.
Understanding the part numbering system for each
component, will identify the application in which that part is
used.
1
Halos Bracket Hose
HA-4### BR-DR## HS-1###X
HA = Halo BR = Bracket HS = Hose
4 = Mount Type, Direct Mount DR = Direct Mount 1### = Hose Length
### = pressure set
080 to 120 by increments of 5
## = stud diameter
P or N for trailer application
X = end connection (S or U)
Inner or WB = S
Outer = U

Tractor Hub Measurements
• Tractor hub measurement and stud diameter?
• If the application has Flowbelow aerodynamic wheel
covers, what are the offset measurements?
