PRO Shaft Seal 1-1/2" Shaft & 2-1/4" 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.

Guess illnhave to buy 2 more of this amazing sunscreen. No white residue, no irritation. Goes on smooth and absorbs very quickly.

Great sunscreen! Protects from blue light as well as UVA UVB.
Size: 1.7 Ounce (Pack of 1)
Great product! It’s a tad greasy so I mix it with other facial sunscreen that has a drier texture and the combo feels great on my skin and gives me a glow. I love that Cocokind protects from blue light too!

Works great and non-toxic
Size: 1.7 Ounce (Pack of 1)
I love this sunscreen. It rubs in smoothly with no pilling. It leaves a slightly dewy finish without being greasy. On my slightly olive skin, there is a tiny white cast at first, but it quickly disappears. It is free of toxic chemicals. It’s more expensive than some lotions but I find it to be worth it.

Irritated skin and too expensive
Size: 1.7 Ounce (Pack of 1)
It’s a good sunscreen. I like the smell and the consistency. However, I live in Denver, CO and it didn’t seem to protect my skin as much as I would like. It also eventually started drying out my skin and gave me a small rash that cleared up as soon as I stopped using it. This could be my personal experience, but it was too expensive and too small of a tube for me to justify continuing use.
