The CS19-F profile is a premier asymmetric single-acting rod lip seal specifically engineered for reciprocating and swivelling movements in aggressive chemical media and high-thermal environments. This high-performance SE-Seal is energized by a precision-engineered Cantilever V-Spring (Finger Spring) inserted into the U-cup groove, providing a flexible sealing lip with large spring travel to accommodate coaxiality fluctuations and "breathing" hardware. As a reliable interchangeable solution, the CS19-F serves as a high-quality alternative to Variseal® M2 and a direct replacement for FlexiSeal® NLA designs, ensuring excellent static and dynamic leakage control across wide temperature ranges.
