PSS Shaft Seal Maintenance Kit - 1-3/4" Shaft - 2-3/4" Stern Tube

PSS Shaft Seal Maintenance & Parts Replacement Recommendations suggest, as with any rubber hose below waterline, the PSS bellows must be inspected on a regular basis for any sign of wear, aging or chemical deterioration.

• PYI suggests preventative maintenance
• The PSS bellow should be replaced in six year intervals
  • During bellows replacement it is recommended the O-rings & set screws in the stainless steel rotor also be replaced
  • Bellows may need to be more frequently inspected in an environment where non-sealed batteries emit sulfuric acid
  • Sulfuric acid vapor will accelerate rubber deterioration, as will an ozonater
• PYI offers a Maintenance Kit that includes the items you need to properly maintain your PSS Shaft Seal
