Manufactured from high-grade NBR bonded to a precision steel cage, the CFKS GA seal strikes an optimal balance between mechanical toughness and fluid compatibility. NBR offers superior resistance to petroleum-based hydraulic fluids, mineral oils, and grease, ensuring the lip geometry retains its memory and tension over prolonged duty cycles. For high-temperature or aggressive chemical environments, custom formulations in FKM are available, providing thermal stability up to 220°C and resistance to synthetic media without compromising scraping efficiency.

Installing the GA series requires an open-groove housing design where the seal is press-fitted into place using an arbor press or uniform driving tool. Ensure the housing bore is clean, deburred, and lightly lubricated prior to installation to prevent metal casing distortion or lip damage. The rigid outer metallic frame eliminates the risk of seal blow-out or axial displacement during heavy shock loads. Regular maintenance simply involves visual inspection of the wiping lip for excessive abrasive wear; timely replacement during routine cylinder overhauls prevents costly rod scoring and unscheduled downtime.
