The PSS Shaft Seal is a mechanical face seal that uses a self-aligning high density carbon-graphite stator to ensure a 100% watertight seal with proven reliability.
The carbon stator is held against an O-ring seated stainless steel collar by a tough, chemical and fuel resistant nitrile rubber bellow.
This seal will eliminate shaft wear and minimize corrosion.
