The SE19-FS is specifically engineered for high-integrity sealing in cryogenic valve and vacuum compressor applications. By integrating a high-load Helical Spring , this model provides the highest progressive spring load to compensate for thermal contraction, ensuring a gas-tight seal even in absolute zero environments. Our tailor-made rounded lip geometries promote a thicker lubrication film, significantly reducing wear and extending service life in slow dynamic or static rod systems.
