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.

Not A Walking Shoe
Size: 9.5, Color: Black/British Tan
In the photo online this shoe looks like it will be very comfortable. Kind of a classy Coach's Shoe. Also in the photo the heel portion of the sole looks thick and supportive. I bought them thinking they would be my go-to travel shoe. Wrong. This is not a comfortable shoe for extended wear. Short durations, OK. The main problem is that the sole is very thin and flexible in all directions. There is no, as in zero arch support, plus that thin heel means that you tend to rock back on your heels and it feels like you're pounding the pavement. I've worn once and I'm very disappointed. They look great, definitely high quality materials, but using them for the intended purpose of travel.... fah get about it. If you're looking for a good looking shoe to wear around the gym and you don't intend to use the treadmill, or elliptical, then this is the shoe you want. They would definitely be returned if I hadn't already worn them outside.

Waterproof perfect as travel fountain pen case
Awesome very small size waterproof bag. Purchased to use as a travel case for my fountain pens and ink (just in case). Although I have never had an ink accident, I wanted something compact enough to use in a small cross body bag without wasting space for the sake of an extra measure of assurance I wouldn't end up wearing my ink. NOTE, I do not use the disposable ink cartridges only adapters or dropper fill. So if I were to experience an ink mishap it would be more than just a tiny amount of permanent ink. The bag seems to be very well made. It is exactly as described, the only thing that may not be obvious is that the material is quite robust and there is no real give. So it works perfectly as a pencase and for a passport or smaller notebook. I would note recommend using it for something thick or round, like an apple or a larger size bottle of ink. However for a syringe full of ink along with half a dozen fountain pens it's superb! Will definitely buy again when need arises. This would also make for a great safe case for a smaller phone. However current flagship phones will not fit through the limiting zipper length. A future improvement of having the zipper go just around the corner to allow full length access would be an awesome improvement which would then be perfect for a newer model cell phone.
