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.

Kept Her Attention Immediately
Format: Hardcover
I bought this for my niece’s little daughter, and she absolutely loved it.
She played with it, looked through it over and over, and was completely engaged with it, which honestly says everything. Keeping a little child’s attention is not always easy, so I was very impressed with how much she enjoyed it.
The quality is excellent too — very vibrant, colorful, durable, and beautifully made. It feels sturdy enough to hold up well with little hands while still being attractive and fun to look at.
Overall, a wonderful purchase and a really great gift for a child.

Fun, Interactive Sound Book for Toddlers
Format: Hardcover
My daughter loves this book and especially enjoys pushing the buttons to hear the animal sounds. We aren’t quite old enough to match the pictures to the buttons yet, but she has so much fun pressing them and mimicking the animal noises, which makes this a great early learning experience.
The bright Eric Carle illustrations are engaging, and the interactive buttons keep little hands busy. A wonderful toddler-friendly sound book that grows with your child and encourages sensory play and language development.

Great Book for Engagement and Following Directions
Format: Hardcover
Great book! I use it to teach animals and following directions, and it keeps the kids engaged. I covered mine with contact paper because it is delicate. The pages are nicely printed with a glossy finish, but they are made of thin paper.
