PRO Shaft Seal 2-1/4" Shaft & 3-1/2" Tube

The PSS PRO Shaft Seal is a mechanical face seal utilizing our proven stainless steel and carbon sealing components but adds reinforced silicone bellows, a secondary shaft retention collar, 316 Stainless Steel hose clamps (rolled edges and non-perforated), and an optional Nitronic 50 rotor upgrade (for highly corrosive environments). Designed specifically for applications that will require increased durability and resistance to harsh, corrosive, high pressure, and otherwise demanding environments. The PSS PRO Shaft Seal is a specialized mechanical seal suitable for various applications, with unmatched performance.

As with PSS Type A & B Seals, The PRO Shaft Seal is a mechanical face seal. The sealing surface is created between the flat surfaces of the rotating stainless-steel rotor and the stationary carbon flange. The stationary carbon flange is attached to a heavy-duty silicone bellows attached to the vessel’s stern tube (shaft log), with 316SS hose clamps. The stainless-steel rotor is fitted on the shaft in front of the carbon flange and is used to compress the bellows, the rotor is then secured to the shaft with set screws, and the shaft retention collar is installed. This compression (pre-load) maintains constant contact between the two mating faces of the stainless-steel rotor and carbon flange, allowing the PSS to compensate for the variable axial movement due to propeller thrust. In addition, the carbon flange is over-bored to the shaft diameter allowing it to "float" around the shaft and thus compensate for most misalignment and vibration from the drive-line. The stainless-steel rotor is sealed to the shaft by two O-rings recessed into the rotor's bore. These O-rings rotate with the shaft and the stainless-steel rotor and therefore do not experience wear during operation.

This stuff has a strong scent. Sort of beachy, sunscreen smell, which is not my favorite. It is definitely shimmery. I used this for a hawaiian themed party. It was pretty! It dried down fairly quickly. I did place a towel down in my car before I got in it just in case some of it came off the back of my legs and got all over the seat. I wear black pants to work most days, and didn't want a glitter butt every day.

LOVE this product! Bought few bottles because they were on sale. You get such a nice bronze glow. I dont just use on face I put around collar bone area, legs and arms. Subtle glitter and glisten. You dont need a lot. One pumps is small amount, but goes a long way. I get lots of compliments when sun or light hits just right. LOVE LOVE LOVE
