The PSS Shaft Seal is a mechanical seal that uses a self-aligning carbon-graphite stator to ensure a 100% watertight seal with proven reliability. This seal will eliminate shaft wear and minimize corrosion.

These type of seals are unaffected by engine motion or vibrations. The result is a 100% watertight and totally maintenance-free seal.

Available for shafts from 3/4″ to 3 3/4″ (22mm to 95mm). Larger sizes are available upon request. See sizing chart.

All mechanical seals look very similar. There is, however, a big difference in materials uses in the components and subsequently in the way the seals will perform.
