Advantages of an R.E. Thomas self-aligning shaft seal:

No rubber bellow to tear or lose compression and cause flooding.
No stainless rotor to slip on the shaft and cause flooding.
No carbon stator (sealing face) to crack and cause flooding.
No cheap nylon hose fitting to snap or break off and cause flooding.
No o-ring or lip seals to fail and cause flooding.

Compatible with most stern tube arrangements or with our industry leading intermediate shaft bearing assembly. Refer to our sizing guide to determine the correct seal based on your boat’s shaft diameter and stern tube/shaft log O.D. (outside diameter).
