Medium-pressure single-lip oil seal


Medium-pressure single-lip oil seal  

Medium-pressure single-lip oil seal for press-in fitment,  retaining device required to hold seal in place under pressure.

The rubber OD provides better static sealing.  The thermoplastic reinforced design ensures concentric fitment and increased corrosion resistance over traditional seals.  Optimized seal lip design uses a garter spring to maintain a constant radial lip load, thus ensuring optimum sealability.  This seal is also available in small quantities for repairs and seal replacements within 1 to 3 days.  For dirty, dusty or polluted environments, our R2HP1 style with additional dust lip should be used.
