Rocol Silicone Grease 85 g Tube, White, NGLI Grade 3/4, Operating Temp -40°C to 200°C 12251

Rocol 12251 Silicone Grease 85 g tube, branded as Sapphire Aqua-Sil, is a premium silicone grease formulated for reliable long-term lubrication across various industrial and maintenance applications. It is a white, translucent grease with inorganic colloid thickener delivering high performance under a broad temperature span from -40°C to 200°C, with short-term tolerance up to 220°C. Suitable for light to medium duty uses, it excels in environments requiring chemical and water resistance, including salt water exposure.

This grease offers outstanding dielectric strength making it versatile for use as an electrical filling compound and is non-toxic, suitable for both hot and cold potable water systems. Its viscosity characteristics (700 cSt at 40°C and 380 cSt at 100°C) ensure excellent flow and lubrication behaviors for seals, O-rings, slides, and slow-speed bearings.

Sapphire Aqua-Sil is particularly favored for rubber assembly lubrication, such as seals, O-rings, gaskets, and washers, but is not compatible with silicone rubber. It also works well with most plastics, preventing wear and extending service intervals through an extremely long wet life that reduces re-lubrication frequency and may potentially offer lifetime lubrication.

Common industrial uses include Water Authorities, Gas and Plumbing industries, pneumatic and hydraulic valve maintenance, tap and shower washer lubrication, and toys involving rubber or plastic components. Its high resistance to chemicals, oils, and gases, combined with water resistance, makes it a reliable and versatile lubricating solution for these sectors.

The product is manufactured in the United Kingdom and meets the Water Regulations Advisory Scheme (WRAS) standard, bearing certification number 1203533, confirming its suitability for potable water contact applications.

Operates between -40°C and 200°C for long-term use with short-term tolerance up to 220°C. Highly resistant to chemicals, oils, gases, and water exposure. Non-toxic and approved for potable water applications. Suited for lubricating seals, O-rings, and slow-speed bearings.
