Deep Sea Seal Thursday, August 7th 2008

The Deep Sea Seal is a propeller shaft sealing system as an alternative to a stuffing box and comprises of two components. A stationary SEAT that fits onto the inner end or the stern tube and the rotating SEAL that attaches to the propeller shaft. The rotating seal runs against the stationary seat to give a watertight "drip free" seal. Both are moulded from tough, oil resistant chloroprene.

The set number you require will be determined by the Shaft size, the diameter of the Stern tube and the speed of the propeller shaft, as indicated in the table below.
