High Temperature Vacuum Silicone Grease For Valve Lubricant
YBS-1674 silicone grease is refined using a special process with silicone powder, inorganic thickener, dimethyl silicone oil, structural stabilizers, and other additives. It has both water-resistant and lubricating/sealing functions. It is safe and non-toxic, possessing high physiological safety, while also exhibiting excellent heat resistance, oxidation resistance, and electrical insulation properties.


High Viscosity Base Oil
The excellent oil film composition of the base oil endows the grease with superior anti-friction and anti-wear properties. It also boasts excellent high-temperature performance and adhesion, a low coefficient of friction, and strong load-bearing capacity.
Excellent Plastic Compatibility
It has good insulation properties, strong material adaptability, and is compatible with most plastics and silicone.
Excellent Corrosion Protection Performance
Excellent rust and corrosion resistance, effectively reducing the maintenance cost of lubricated parts by 60%; copper-colored, stain-free, resistant to acid and alkali corrosion and does not corrode metals, and resistant to hot and cold water.
Good Dielectric Properties
Good dielectric properties ensure the safe use of electrical appliances.

Operating Precautions
■ Preparing the application component: New components are typically treated with organic rust-preventive oil or lubricated with grease during storage to prevent damage. Before use, the carrier should be inspected for damage.
■ Cleaning before use: Corrosion-preventive coatings and rust-preventive metal surfaces also prevent grease adhesion. However, they can oxidize and harden, producing debris that can contaminate the grease. The component can be cleaned with alcohol or gasoline.
■ Sealing silicone grease must not be mixed with petroleum. Any petroleum residue on the carrier must be thoroughly cleaned before use.
How To Use
■ Apply a thin, uniform layer of silicone grease to clean and dry surfaces. Remove dust, oil, and moisture before application to ensure proper adhesion and sealing performance. Assemble components immediately after application.
