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.

It is breakable
Although it was an exciting toy, it was not long lived. I can’t say it’s as durable as it claimed to be. My 12 lbs dachshund chewed through it in less than a day. He had fun, but there were too many little pieces he tore off. Not worth the risk of him ingesting them.

The dogs like it very much, it produces a lot of noise.
Size: Large, Size: Large
I’m rating this based on my dogs’ response to this toy – they absolutely love it, and it has seen more use without damage than any of their regular throwing toys. At the same time, unless you enjoy, REALLY ENJOY the sound of crunching water bottles, you may not like having this ball in the house. Pros: The rubber outer shell of the ball is durable, and can survive both chewing and pulling forces (as a note, my dogs do not concentrate on chewing - they use it more for play games). It’s big enough for my dogs to play tug of war with it, hooking their teeth in the mesh, and they since it bounces around if they drop or kick it, it makes the game more interesting than rope. They did crush the interior plastic, but they don't really seem to care. It’s much more engaging than a normal ball, and can be modified to hold treats, sticks, rope elements and other external bits, which my shepherd mix loves; he gets bored easily and frequently, and this can actually entertain him. Cons: This toy is loud, and produces repetitive crunching sounds. It is apparently really engaging to chew, and my dogs will produce the horrid plastic crackling up to half an hour at a time. If you let your dogs in and out, it would make a fine outdoor toy, but since I have a dog door, it migrates around to pretty much wherever the dogs are. I kind of hate it, but will probably buy another if they break this one since they enjoy it so much.

Very durable and my Heeler's fave inside toy
Size: Large
My red Heeler loves these balls, second only to Tennis balls but she destroys those within minutes and they are outside only. This is her inside ball. She is hard on toys and has the strongest bite of any dog I've had (shepherds, collies, weimaraners, retrievers, Labs) yet these continue to last. She catches the ball, we play tug of war with it (she places it in hand hand and pulls only when I have a firm grip, she shakes it and flings it. The rubber outside even outlasts the water-bottle like plastic piece inside. Steps holds the ball with her foot and pulls on the rubber with her mouth, stretching it to sometimes twice its size. I pull while shes pulling. This thing gets abused daily and keeps on going. Its the most used toy and she brings it to me to play with every day. Each ball lasts about 6 months before the inside ball is toast and the outer rubber is finally starting to tear/break. which for me in an incredibly long time. If this ball is available to play, she wants it over all others. Shes NEVER gotten a piece off to actually swallow and that alone is worth the price.
