Shaft Seals (Grease & Oil)
Dripless, dependable shaft sealing
A good shaft seal keeps water out and oil in, and does so quietly for years. We supply and specify Duramax dripless face seals, Super Seal oil-type seals, and traditional water-lubricated stuffing boxes — matched to the shaft size and vessel duty cycle.
Every seal comes with installation instructions, and we offer phone support for your installer during fit-up.
