We offer PSS Shaft Seal Maintenance Kits to keep your PSS Dripless Shaft Seal in perfect working order.
As with any rubber hose below the 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 bellows should be replaced in six-year intervals. During bellows replacement it is recommended that the O-rings and set screws in the stainless steel rotor also be replaced. The 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.
Maintenance Kits include the items you need to properly maintain your PSS Shaft Seal. Included in the kit is one PSS bellows, two O-rings, five set screws, four new hose clamps and an Allen key. Select the appropriate Maintenance Kit for your application by choosing the correct shaft and stern tube dimension.
- One (1) PSS bellows
- Two (2) O-rings
- Five (5) set screws
- Four (4) new hose clamps
- One (1) Allen key
