PSS SHAFT SEAL

P.S.S. (Packless Sealing System) Shaft Seals

A stationary carbon flange is held in contact against a stainless steel flange, which rotates with the prop shaft. The high-density carbon/graphite flange is attached to the boat by a nitrile bellows which, with the help of water pressure, produces constant pressure between the carbon and stainless flanges. This mechanical seal is 100% watertight and virtually maintenance-free. Made from space-age carbon composites, heavy-duty nitrile O-rings, nitrile bellows, and Type 316 stainless rotor and fasteners, P.S.S. Shaft Seals are durable, strong, resistant to high temperatures, saltwater, UV radiation and petroleum-based products and corrosion. Both propeller shaft diameter and stern tube (shaft log) diameter are necessary when ordering. Sizes not listed are available by Special Order.

    Comments about P.S.S. (Packless Sealing System) Shaft Seals:

    Installed the PSS shaft seal in 2005 for the first time on a 40ft steel sail boat I'd just purchased. Keeping the bilges water free was a premium consideration for this purchase. Sailed/motored from Mexico north to Canada, Alaska then south to California and west across the Pacific to Australia. Never let us down. However, in the last 2 years of cruising the Australian eastern seaboard, we've gone up and down many muddy rivers and think we've scrached the shaft somewhat as the PSS seal is now leaking slightly (no great water leaks as such, mainly salt residue around the shaft). We plan to haul out very soon and decided to purchase another PSS shaft seal in case we had to replace it. Didn't want to rely on fixing the problem with the old seal, in case it had got damaged somewhat.
    All in all, a good, watertight shaft seal which I would recommend to other sailors.
