Air compressor piston seal is designed to ensure that pressurized fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore. In addition, the choice of piston seal depends on how the cylinder works. The best sealing capacity of a double-acting cylinder, capable of sealing dynamic pressure from both sides (bidirectional), is achieved by choosing a double-acting seal. Due to the design of the piston, the two single-acting seals on the piston are double-acting cylinders that can easily cause malfunctions. The reason is that there may be high pressure between the seals. Wear on the carbon is taken up by the action of the spring and water pressure continually forcing the segments into contact with the shaft, while the wedges move outwards. Thus wear of the carbon segment takes place while they still maintain an effective seal.
