The PSS Shaft Seal is the leading marine mechanical seal globally, installed as standard equipment by reputable boat builders and recognized as the premier retrofit seal on the market. Certified by Bureau Veritas, ABS, and Rina, the PSS Shaft Seal eliminates the maintenance and costs associated with traditional packing type glands, helping prevent water in the bilge (100% watertight) and reducing wear on the propeller shaft. It can be retrofitted for shafts ranging from 3/4" (20mm) to 6" (150mm).

As a mechanical face seal, it creates a seal between the stainless steel rotor and the stationary carbon flange, which accommodates misalignment and vibration. Regular inspections of the PSS bellows are recommended for signs of wear or deterioration, with suggested replacements every six years. During this process, it's advisable to replace the o-rings and set screws.
