Seiken chemical products

Seiken genuine brake fluid is a high-quality, high-performance non-mineral oil brake fluid that comply with the JIS standard (except BFR), as well as meeting standards such as FMVSS and ISO. With boiling point performance exceeding JIS standard values, we prevent the phenomenon of vapor lock and protect car safety.
BF3, 4, and 5 are for regular cars, BF6 is for European cars, and BFR is for racing machines.

A double-diluted long-life coolant. Regular replacement is necessary to take full advantage of winter freeze protection, summer overheating protection, and maximum corrosion protection performance of the cooling system metal.

For passenger cars and small freight vans, we have achieved tremendous longevity of 5 years, or 100,000 km before total replacement. Pre-diluted with purified water, and so can be used as is. Prevents corrosion of aluminum, copper and iron, using a heat-resistant, highly stable non-amine additive, achieving long-term stability of quality and performance. Suppresses cavitation damage and prevents damage to the cooling system.

In a short time, possible to restore the anti-corrosion and defoaming performance of coolant that has deteriorated due to use. The easy-pour shape can be used without spilling on the engine. A pale yellow liquid that does not mix with other color liquids.

Improves lubrication of piston cup and piston and brake cylinder, and facilitates assembly. Completes the setting, preventing the initial leak phenomenon and abnormal wear of pistons.
