PSS Shaft Seal Packless Sealing System is a dripless stuffing box and packing gland replacement for sailboat and power boat drivetrains.

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. Available for shafts from 3/4" to 3 3/4" (22mm to 95mm). Larger sizes are available.
