SAPPHIRE® Aqua-Sil - Highly resistant silicone grease for long term lubrication ROCOL® SAPPHIRE Aqua-Sil is a translucent, non-toxic grease that has been designed for the lubrication of seals, ’O’ rings, slides, slow speed
bearings and other similar light to medium duty applications.
SAPPHIRE Aqua-Sil has a high dielectric strength, is resistant to chemicals, oils and gases and can be used as an electrical filling compound. Features and Benefits: • Excellent wide temperature resistance – ranging
from -40°C to +200°C and it can protect up to +220°C for short periods.
• Outstanding resistance to chemicals, oils and gases far superior to standard greases.
• Excellent resistance to water, including salt water, ensuring components are protected even in submerged conditions.
• SAPPHIRE Aqua-Sil is approved for use in both hot and cold potable (drinking) water.
• Suitable for use as a rubber lubricant for most rubbers (not suitable for silicone rubber).
• Commonly used for the assembly of rubber seals, tap washers and ’o’ rings.
• Ideal lubricant for most types of plastics.
• Extremely long wet life reducing re-lubrication
frequencies and in some cases can be used as a
lifetime lubricant.
• High dielectric strength making it ideal for use as
an electrical filling compound

• SAPPHIRE Aqua-Sil is designed for long term, light, and possibly lifetime, lubrication depending on application.


• SAPPHIRE Aqua-Sil is particularly suitable as a rubber assembly grease on seals, ’O’ rings, gaskets and washers.


• SAPPHIRE Aqua-Sil is ideal for use where a high performance, water and chemical resistant lubricant is required such as Water Authorities, Gas & Plumbing, and most other industries where a multipurpose water and chemical resistant silicone grease


• is required.


• SAPPHIRE Aqua-Sil excels in applications such as the assembly or repair of pneumatic/hydraulic valves & cylinders, tap & shower washers, valve seals, toys and many other applications where rubbers or plastics require a light, colourless, non-toxic lubricant for long term or possible lifetime lubrication.
