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.

Best organizer with a water spout to keep them counter dry!
Color: Black - 9.25″, Color: Black - 9.25″
I am thoroughly impressed with this product. I tried a product that goes over the middle of the sink and it blocked everything off and would always fall off in a funny ways. I had no room for my pots and pans and started getting irritated with it. This is up and out of the way has a little spicket to drain off the water and as you can see I got all of my sponge and soaps in the same spot which is wonderful cleaned off my counter beautifully. I chose the color black to blend in with my black countertop and also to look nice and clean on the counter. One of the best organizers I have ever found for a countertop. It's sturdy metal so far seems rust resistant, but I haven't had it long enough to know for sure. Mobilize easily to clean. Fabulous little sink caddy. I highly recommend to those of you that like to be organized and keep your counter nice and dry, and still arrange things so that it can be out of the way.

No Rust, No Fuss, A simple but great Sink Item
Color: Black - 9.25″
For years I just had my sponges just laying on or around the sink but this year I decided I needed something to hold the soups and cleaning detergent. Along with not being too pricy and that is how I stumbled upon this sink caddy it has worked amazingly. It holds the detergent, sponge, and tube brushes with no problem and any water is drained out from the little spout underneath it. You can adjust the dividers so you can have how you want things separeted from each other and with the bottom being plastic you don't have to worry about getting any rust there. If you need something to make more space around your sink this item will help you.

Functional neat and worth it!
Color: Navy Blue - 9.25″
This caddy has been even more useful than I expected. It instantly made my kitchen look cleaner and more organized compared to having wet sponges sitting on the sink. My counters look much tidier now, and the sponges dry out much better. It may seem like a small addition, but it really makes a big difference.

Makes the Sink Area All the More Organized
Color: Silver With Towel Rack - 9.25″, Color: Silver With Towel Rack - 9.25″
At first glance I'm sure most people might think this kitchen accessory is kind of silly; a caddy for your sponge and dish soap? But honestly, it makes the kitchen area look at the more organized and keeps things in place. I sprung for the model with the towel holder because I always feel weird about bacteria sitting in the wet microfiber cloth that I use for cleaning the kitchen countertop and my dining table. The little dowel allows it to dry very quickly. The holder can be configured in a few different ways to accommodate your cleaning items. I like that it's wide enough to comfortably hold the large bottle of dishwashing soap I buy and it's the perfect width for Sponge Mommy/Daddy sponges. I've had it less than a week and haven't had to wash it yet, but it seems like it will hold up well in the dishwasher and won't rust. Since I don't have any sponges on a handle, I may use the removable compartment for those (that you can see on the left in my photo) for other kitchen tools.
