The PSS Shaft Seal is the number one selling marine mechanical seal worldwide and is installed as standard equipment by many of the worlds most reputable boat builders / yards. The PSS Shaft Seal is also recognized as the premiere retrofit (aftermarket) seal on the world market. Certified by Bureau Veritas, ABS & Rina: Boat builders / yards recognize the advantages and value of installing the PSS as it eliminates the maintenance, constant adjustment & cost associated with traditional packing type glands. Aside from these benefits, the PSS Shaft Seal helps to eliminate water in the bilge (100% water tight) & wear to the propeller shaft. The PSS Shaft Seal can be easily retrofitted and is available for shafts ranging from 3/4" (20mm) to 6" (150mm).

The PSS Shaft Seal is a mechanical face seal that is created between the flat surfaces of the rotating stainless steel rotor and the stationary carbon flange. The stationary carbon flange is attached to the vessels stern tube with hose clamps and the carbon flange is attached to the front side of the bellows with hose clamps. The stainless steel rotor is fit on the shaft in front of the carbon flange. The stainless steel rotor is used to compress the bellows before the collar is secured to the shaft with set-screws. This compression (pre-load) maintains contact between the faces and allows the PSS to compensate for the thrust from the propeller. The carbon flange is bored larger than the shaft diameter allowing it to "float" around the shaft and thus compensate for most misalignment and vibration problems. The stainless steel collar is sealed to the shaft by two o-rings that are recessed into the bore of the collar. These o-rings rotate with the shaft and stainless steel rotor and do not experience wear during operation.


**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 as preventative maintenance that the PSS bellow 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.

The Maintenance Kit includes the items you need to properly maintain your PSS Shaft Seal. Included in the kit is one (1) PSS bellow, two (2) O-rings, five (5) set screws, four (4) new hose clamps and an allen key.

Good Stuff!
Flavor Name: Mint, Size: Pack of 1 (4 Ounce)
I have been trying different non fluoride toothpaste and I think I have found a winner! This toothpaste leaves my teeth clean and my mouth fresh! The texture is great and I am impressed with the ingredients. The price is a little pricey but you only need a pea size amount. Very easy to use and does not run out of the tube like some non fluorides Ive used. Definitely will buy again!

I love this toothpaste! I have tried several hydroxyappetite pastes and this is by far my favorite. My teeth feel clean, I have zero sensitivity issues anymore and my dental check ups are very good.

Pineapple and papaya
Color: A - Magic Mint (Pack of 3), Color: A - Magic Mint (Pack of 3)
I like it okay. I will use all of it but I am unsure if I will buy it again. It foams very little. I feel like I use more than I do with other pastes/gels. My mouth feels clean without having that too minty/medicinal taste from traditional flouride pastes. It comes out of the tube easy and sticks to my brush. I didn’t know until after I purchased it that there is papaya and pineapple extracts. There IS a photo in the product description that says this and I neglected to click through them all. I have two members in my household that are allergic to those ingredients so I have not had them try it. The only taste is a mild mint though. I think the whitening effects of nanohydroxyapatite pastes is much better than other popular brands that boast “whitening.” My teeth simply look whiter and shiny.
