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.

Happy with purchase
Color: White Floral, Size: 3X-Large
This shirt is soft and comfortable. I love the sleeve length. The print is nice. It looks nice with jeans, casual pants, and skirts making it versatile. My only complaint is that I have already noticed fading after two washes.

Love these tunics!
Color: Aprioct Boho Yg9, Size: XX-Large
I absolutely love these tunics! They are very figure flattering & so soft & comfortable to wear. The material is on the thinner side so they are great for warmer weather. I have very sensitive skin so many fabrics irritate me but this one is fabulous. I would wash on gentle & hang to dry to keep fabric looking nice. After wearing the first one, I ordered 3 more…

Pretty Tunic Top
Color: Willowfloral, Size: X-Large
Very happy with this tunic top! Long enough for me to feel good about wearing it with leggings, but not SO long it feels like a dress. Really good V-neck, not just a little notch at the top that some brands call a v-neck. I ordered the teal floral XL and was very happy with the fit and drape. I'm a size 18W with a 42D bust and a chubby waistline. I often end up in XXL or 1X tops, but this fit well as an XL. Nice feel to the material and a bargain at the price!

Very flattering in my opinion
I'm 5'6 and no hips, so I really liked that the length is a little longer and flares a little at the hips giving my chunky but not curvy figure some illusion of a girlish figure. The pattern and colors were pretty & I'd say pretty close to the ad. Great blues and a coral/peach ... not sure my camera did it justice. I like the pleat at the back ... I feel that it minimizes the bra bulge that can happen at times. I stepped out after try on and my guy said it looked great (he's a truth teller with clothes) so that made me feel better because sometimes I see what I want to see at first & later see the flaws. I do see the case instructions ... getting used to hang to dry all things lately. Feels a little more nylon-ish but not bad. Its not super thin and light where I think it's a clingy thing. Really do like this shirt
