Product description

The outer manifold ring is a high-precision sealing component used in the revolving pneumatic distributor of professional Snap-On tire changing machines. Often associated with engineering specification EAA0338G76A, this ring is critical for maintaining an airtight seal between the stationary and rotating parts of the air distribution system as the turntable spins 360 degrees. It is engineered to minimize friction and wear, ensuring that pneumatic pressure is delivered consistently to the rim-clamping cylinders without leaks. A worn manifold ring can cause a significant drop in clamping force, leading to the risk of the wheel slipping during high-torque tire mounting. This replacement ring is made from high-performance materials designed to handle the continuous motion and pressure typical of a high-volume tire service center, ensuring your equipment remains safe and productive.
