Tire Inflation Cage
WS-35026
New
High Capacity Tire Inflation Safety Cage can eliminate that danger while automatically inflating and regulating pressure. When using the system, a steel cage prevents wheel fragments from escaping in the event of an explosion.

CAUSES OF WHEEL/TIRE ASSEMBLY EXPLOSIONS
Airplane wheel/tire assemblies are inflated to high pressures, often in excess of 200 pounds per square inch (psi). Because the pressure in a nitrogen bottle or tire-servicing cart can be as high as 3,000 psi, connecting the nitrogen source directly to the wheel without a regulator subjects the wheel to sudden high pressure that can exceed the design limits for the wheel, the wheel tie bolts, or the tire. Consequently, the wheel, the wheel tie bolts, or the tire can explode and become projectiles (see fig. 1, above), causing severe injuries, dismemberment, or death.
In most of the reported cases of related injuries, the wheel/tire assembly that exploded was a nose wheel on a smaller-configuration airplane such as a 737. These tires present a greater risk because their smaller size means they reach dangerous pressures faster than the tires on main landing gear.
TIRE INFLATION PRECAUTIONS
Whenever an airplane tire is being serviced, three layers of protection are normally in place to protect maintenance workers from wheel fracture:
- A pressure regulator on the nitrogen supply.
- A pressure relief valve on the tire inflation tool.
- An overinflation pressure relief (OPR) valve installed in the wheel.
