PSS Seals Dripless Shaft Seals
Genuine PSS & PYI dripless shaft seals

Tell us your shaft and stern tube.
We'll find the seal that fits.

PSS shaft seals are sized by your propeller shaft diameter and your stern tube outside diameter. Enter both and we'll work out every PSS configuration that seals your setup — and we'll mix and match parts to make your exact size work.

How it works

  1. 1

    Measure two things

    Your propeller shaft diameter and your stern tube outside diameter. Metric or imperial — either is fine.

  2. 2

    We match it

    Our seal finder returns every compatible PSS configuration, including ones we assemble from separate rotor and bellows parts.

  3. 3

    Order with confidence

    Pick the option that suits, add to cart, and we'll dispatch the correct seal — assembled and ready to fit.
