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.

Perfect for the Price!
Color: Greige, Size: 13"D x 23.7"W x 32.7"H
The bar cart was very easy to put together. I can be "mechanically challenged" and was able to do it myself LOL
It's nice and sturdy, the wheels roll smooth when you move it. The size is perfect for the small wall I have it against.
I have several bottles of liquor and bartending mixer set on top, and about 20 various glassware on the 2nd shelf.
The bottom shelf is taller, and does let you stand larger bottles down there. The one racks will only for the smaller size, but does hold them well.

Decent bar cart, but very annoying assembly
Color: Marble White, Size: 13"D x 23.7"W x 32.7"H
I think it looks nice and is decent value, but this thing is a pain to put together. Instead of just sending 3 shelves, you get 6 pieces to connect together to make 3 shelves. On top of that - they don’t even really connect. It would be 1000x easier if they added a couple of wooden pegs to connect the 2 pieces together. Instead, you have to do a balancing act which is tedious as can be. I ended up super glueing 2 of the 3 shelves togethers after how annoying the first was, so I would highly recommend you do the same.
The whole process of putting it together feels like a balancing act. For something so small, it’s about as annoying as possible to put together. Nearly every step requires you to balance something and screw it in. Most of this would be alleviated if, as I said, it was just 3 pieces for the shelves instead of 6. But, you get what you pay for. Overall, I can’t complain too much for the price and result, but I wasn’t a fan of building it. It’d also look a little nicer if each shelf didn’t have a crack going through it.

Very pretty
Color: Black, Color: Black
This sink caddy is very pretty. It is easy to use. It has slots for brushes and whatnot. Keep in mind that not all soap bottles will fit in it though. I had to adjust my soap bottle to fit, so it kind of took up space where I could have put a little more things that same space. If you have round sponges like the ones I have, they can fit where you put the soap dispenser. It just all depends on what size soap dispenser you have in there. The quality has been good so far. It's easy to clean the bottom of the tray. It simply just slides in and out. Very easy. I recommend this.
