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.
We size it for you
No part-number guesswork. Give us two measurements and we return the seals that fit.
Mix & match
One shaft + stern tube can be built from several part combinations. We show every option.
Genuine parts
Authentic PSS & PYI components — the same seals trusted on boats worldwide since 1994.
Australia-wide dispatch
In-stock configurations ship fast from our Australian warehouse, GST included.
