What type of grease does the Type 7950 through-hull deployment require?

The deployment machine sealing section should be filled with Staburags NBU12K. On New machines the sealing section comes pre-filled.

To top up the grease remove one of the grease nipples and apply grease using a grease gun through the second grease nipple, until grease is seen coming out of the first grease nipple (this prevents over pressurisation). Once filled, fit the first grease nipple. Do not cross contaminate the sealing section with non-compatible grease.

Check grease compatibility before using an alternative.
