Castrol Optileb GR 823 greases (previously called Molub-Alloy Food proof 823 FM) were developed for general lubrication of food machinery. They have been approved as “physiologically safe” by the Landesgewerbe-Anstalt LGA Bayern.

Optileb GR 823 greases have also been approved by the U.S. Department of Agriculture (NSF) as “H1” lubricants which can be used in the food and beverage industry even if incidental contact with food products is possible.

• A select base oil blend plus an FDA-approved thickener provide good adhesion, film strength and water-wash resistance even at elevated temperatures. Drip-free characteristics and the off-white colour of Optileb GR 823 greases complement housekeeping efforts in food and related industries.
• A high-performance combination of food-grade additives provides excellent anti-wear protection. The combination of additives and blending techniques maximises rust and oxidation characteristics for effective rust protection and the long service life of the grease.

• Developed to lubricate food machinery in high-temperature applications where incidental contact with food is possible.
• They are recommended for sleeve and rolling bearings in overhead conveyors and other material handling equipment.
• May be applied manually or with automatic dispensing equipment.
• Lighter consistency GR 823-0 grease can be used in gear cases where a non-channeling slump grease is needed to control leakage.
• Temperature application range: – 30°C up to – 120°C

Castrol Optileb GR 823-2 Advantages:

• H1 lubricants acceptable for use where incidental contact with food is possible.
• Very high melting point and non-drip characteristics of this grease minimize product contamination.
• Unique water resistance provides continuous protection even when equipment is washed down periodically.
• Physiologically safe (approved by LGA Bayern) – base fluid and all other ingredients used in GR 823 comply with sections 178.3570 and 178.3620 of the FDA guidelines.

• Optileb GR 823 greases should not be mixed with greases using a different thickener. Lubrication intervals should be increased gradually to ensure complete removal of previous lubricant.
• At higher temperatures (above 100°C) relubrication intervals should be established by inspection.

This product was previously called Molub-Alloy Foodproof 823 FM . The name was changed in 2015
