Spring-loaded, double-lip oil seal

Single-lip oil seal with a solid rubber construction.  Designed to allow fitment in challenging locations.

The optimized seal lip design uses a garter spring to maintain a constant radial lip load, thus ensuring optimum sealability.  The secondary lip acts as a dust wiper for light dirt and fluid exclusion and lube retention.  The solid rubber design allows the seal to snap into a closed groove; alternatively, a retainer ring can be used to hold the seal in place for open groove installation.  Fitment in many challenging seal locations is possible with this design. This style is available in a wide range of elastomers and small quantities for repairs and seal replacement and can be shipped in 1 to 3 days.
