PSS 02-214-334 is a Type A mechanical shaft seal for a 2-1/4" shaft and a 3-3/4" to 3-7/8" stern tube. A rotating stainless-steel rotor runs against a stationary carbon stator, with the compressed bellows maintaining contact between the sealing faces. Two O-rings seal the rotor to the shaft.
Specifications and Contents
- Shaft diameter: 2-1/4".
- Stern-tube outside diameter: 3-3/4" to 3-7/8".
- Uncompressed length: 9.625"; approximate bellows compression: 1".
- Rotor outside diameter: 4.2"; bellows cuff length: 2".
- Bellows material: molded nitrile-PVC.
- Operating limits: 5°F to 225°F (-15°C to 107°C), 10 psi (0.68 bar), and 10,000 shaft rpm.
Fitment and Service Notes
For Type A PSS installations with the dimensions above. Water-feed or vent requirements depend on vessel speed and shaft-log configuration. Inspect the bellows regularly; PSS recommends replacement every six years. Use new set screws whenever the rotor is removed or repositioned.
Have a qualified installer fit the seal with the boat out of the water. Use soap and water on the rotor O-rings, not oil, grease or silicone. At 12 knots or faster, provide the positive cooling-water feed required by PSS; otherwise follow the specified vent or feed arrangement. Reference.
Parts Desk Insight
Measure the shaft and the outside of the stern tube separately, then check the available installation length. A matching shaft size alone does not identify the correct seal. Set bellows compression and arrange the vent or water supply according to the PSS instructions for the vessel.
