Cushion Seal ( CTU, PDF, PEI, AVB )

Pneumatic seals use compressed air to seal the gap in the shaft or piston. It has the characteristics of wear resistance, low friction and low expansion to maintain long-term sealing performance. Air pressure seals for buffering include CTU, PDF, PEI, AVB and other types, which mainly prevent the piston from colliding with the front and rear covers.
