Morris K99 Water Resistant Stern Tube Grease - 500g

Morris K99 Water Resistant Stern Tube Grease is a 500g calcium-thickened marine grease formulated to feed evenly around propeller shafts. It provides water resistance, corrosion protection and sealing performance in wet or humid operating environments.

What is Morris K99 Grease used for?

Morris K99 is designed for marine and industrial lubrication points exposed to water, moisture or humid atmospheres. Its consistency and water-resistant formulation make it particularly suitable for stern tubes, where the grease must distribute evenly around the rotating propeller shaft.

Typical applications include:

• Boat stern tubes and propeller shafts
• Rudder bearings
• Water pumps with packed bearings
• Plain bearings
• Anti-friction bearings
• Industrial equipment operating in wet or humid conditions

Water Resistance and Corrosion Protection

K99 helps maintain lubrication where contact with water could otherwise reduce grease performance or expose components to corrosion. Its sealing properties also help create a protective barrier around lubricated parts.

The grease uses a calcium 12-hydroxystearate thickener and has an NLGI consistency rating of 2/3. It is suitable for operating temperatures between -20°C and +110°C.
