Single-lip medium-duty oil seal

R9HDS


Single-lip medium-duty oil seal

Single-lip medium-duty oil seal for fitment in an open groove. 

Medium-duty oil seal for use in an open housing, even where exceptionally large cross sections are required.  Available in many case and lip materials, this seal can handle aggressive conditions and even pressurized chemicals.  This non-metal reinforcement design ensures concentric fitment and increased corrosion resistance over traditional seals.  This seal is available in small quantities for repairs and seal replacements within 1 to 3 days.  For dirty, dusty or polluted environments, our R10HDS style with additional dust lip should be used.
