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.
Size Table (Inch)Standard sizes listed below are preferred sizes for new design applications; however, we offer any other seal size as required. Seals are available for any shaft diameter size in 0.001 inch increments, including Functional Range.
