Hot Oil Seal

Style: HOS

The HOS is a rotary designed, balanced, single spring seal capable of handling higher operating pressures and temperatures than conventional unbalanced single spring designs. Large coil springs are resistant to clogging and allow the HOS to operate successfully in hot oil applications. The seal is available for fitting both standard and oversized seal cavities.
