SEIVIOVaculub R171 vacuum skeleton oil seal greaseYesMade of high-purity linear perfluoropolyether oil, nano-level ultra-finePTFE thickens. It is refined by adding special anti-corrosion additives. It is a special lubricating sealing material specially customized for skeleton oil seals (lip-shaped rotary shaft seals) in vacuum environments. It takes into account the anti-friction protection of the skeleton oil seal lip and the low-volatility and zero-pollution requirements of the vacuum system. It solves the problem of ordinary oil seal grease evaporating to produce gas and contaminating the cavity under vacuum conditions.
