Constructed with a premium stainless steel housing (available in SUS304 or SUS316), this shaft seal offers unparalleled corrosion resistance and mechanical stability. The rigid metal casing is designed for a precise press-fit into the compressor housing, preventing any bypass leakage even under fluctuating internal pressures. Unlike conventional seals that rely on a metal spring, the PTFE stainless steel oil seal uses the inherent elasticity of the modified PTFE lip to provide radial force. This reduces the risk of spring displacement and eliminates the possibility of spring-related shaft scoring, significantly extending the life of both the seal and the rotor shaft.

Efficiency is critical in modern compressed air systems, and the CFKS PTFE Stainless Steel Oil Seal contributes by offering a significantly lower coefficient of friction compared to NBR or Viton alternatives. This reduction in friction results in lower energy consumption and less heat generation at the sealing interface. Whether applied in oil-injected or oil-free rotary screw air compressors, our PTFE stainless steel oil seal provides a robust barrier against leakage. By choosing CFKS, manufacturers and repair technicians can reduce downtime and lower total cost of ownership through superior sealing technology and industrial-grade material selection.
