R1HP


Medium-pressure single-lip oil seal

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

The thermoplastic reinforced design ensures concentric fitment and increased corrosion resistance over traditional seals.  A tight tolerance reinforcing ring enables this seal to operate at higher operating pressure.  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 R2HP style with additional dust lip should be used.
