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.

Comfortable but smaller than a standard pillow.
Size: Standard (Medium)
The pillow is bit smaller than standard length wise. It takes a while for the smell to go away. Very comfortable pillow.

Remarkable and impressive pillow
Size: Standard (Medium)
The pillow came quickly and was what was expected. After 6 months of chronic neck pain, one night on this pillow has made a world of difference. Please buy one of these if you are on the fence. They are wonderful. Highly recommend.

Not any more breathable than other pillows
Size: Standard (Medium)
I got this in hopes that it would be cooler than other pillows but it seems to hold the same amount of heat. Additionally, as a side-sleeper, it is too thick for me. It is however pretty comfy and seems to be made out of quality material. As other reviews stated, it was smelly at first but that went away within a week.

Great pillow
Size: Standard (Medium)
I love latex pillows. They are bouncy but yet soft. This is my second one. This one is the medium and my first soft. I use soft on top laying watching tv and sleep with medium. No neck pain at all. I have always loved these from years ago. Will always use these only.
