We manufacture high-precision PTFE Piston Rings for reciprocating air and gas
compressors, designed to provide efficient sealing between the piston and
cylinder while maintaining low friction and long service life. These rings are
widely used in oil-free and lubricated compressor systems where reliable sealing
and minimal wear are critical for compressor efficiency.
Our piston rings are produced from filled PTFE grades, including glass-filled
PTFE, carbon-filled PTFE, bronze-filled PTFE and other engineered compounds
selected to withstand high pressures, elevated temperatures, and demanding gas
environments. These materials offer excellent chemical resistance, dimensional
stability, and superior wear performance.
With modern machining facilities and strict quality control, we manufacture
compressor piston rings as per OEM drawings, international standards, or
customer samples, ensuring precise tolerances and consistent sealing
performance.
We manufacture a wide range of piston ring designs, including:
• Angle Cut Piston Rings
• Scarf Cut Piston Rings
• Butt Cut Piston Rings
• Step Cut Piston Rings
• Tangent Cut Piston Rings
• Segmented / Multi-Piece Piston Rings
• Pressure-Loaded Piston Rings
Our piston rings are commonly used in process gas compressors, hydrogen compressors, air separation plants, petrochemical industries, and industrial gas applications where dependable sealing and long operating life are essential.
