The AC-RS130000 compressor rings function as a seal between the piston and the cylinder wall within the air compressor assembly. By maintaining this interface, the rings allow the compressor to build and hold the necessary air pressure required to operate the pneumatic systems found in various cranes and industrial equipment. These components are sized at 2 3/4 inches in diameter to fit specific compressor bores within the air system.
These rings are manufactured by Midland for use in their line of air compressors. They are intended for applications where a precise fit is required to maintain the integrity of the compression chamber. Proper installation of these rings prevents air bypass, which supports the overall efficiency of the pneumatic circuit and ensures that the compressor operates within its design parameters.
Compressor rings serve to contain the compressed air during the power stroke and regulate oil consumption within the cylinder. By providing a consistent seal against the cylinder wall, they help the compressor achieve its rated output while minimizing pressure loss. Regular inspection of these rings is standard maintenance for any pneumatic system to prevent performance degradation.
