PSS SHAFT SEAL 02-134-300Click To Copy HS Shaft Seal - 1 3/4" x 3" x 8 1/8"

P.S.S. Shaft Seals have logged up to 40,000 hours of hassle-free operation! High-density carbon and high-density stainless steel components create a dripless mechanical seal that provides years of use. The stationary carbon flange attaches to the stern tube with a nitrile bellows and is held in contact with the stainless-steel flange that rotates along with the propeller shaft. The force of the compressed bellows presses the flanges together, which creates a 100% watertight seal that is virtually maintenance free. This system is self-adjusting and it eliminates the need for periodic adjustment required by a conventional stuffing box. The seal can be used with a pitted or slightly misaligned shaft because it s designed to compensate for small flaws. Additionally, it won t melt or have a catastrophic failure. P.S.S. makes its seals with space-age carbon composites, heavy-duty nitrile O-rings and bellows and 316 stainless steel rotor and fasteners. The durable seals are designed and manufactured to resist extreme temperatures, saltwater, UV radiation, petroleum-based products and corrosion. Typical break-in after proper installation is one hour. Propeller shaft and stern tube diameter are necessary when ordering. Sizes not listed are available by special order.
