Arai Seisakusho® - Exhaust Valve Stem Seal

Exhaust Valve Stem Seal by Arai Seisakusho®. Valve stem seal (VSS) is installed in the valve guide in the engine head. And it is preventing that engine oil supplied in a head flows into a combustion chamber by going through a valve stem and the sliding surface of guide. However, unlike a general reciprocating oil seal, since the sliding portion requiring lubrication is located on the outside of the seal (on the side where there is no oil), by making a small amount of oil leakage, the lubricating oil can be supplied to the sliding portion It has the ability to replenish.

Arai Seisakusho, the founder of the Arai Seisakusho® brand, was the first who developed and manufactured the oil seal from synthetic rubber. This led to the founding of the company in Taito-ku, Tokyo, Japan in 1956. Through the years Arai Seisakusho enlarged its collection to include high-grade O-rings, reed valves, joint carburetors, sprockets, air dampers, and many more products that received numerous ISO certifications and have provided reliable technology and trust until now. However, the company doesn’t rest on its laurels and continues to innovate and fabricate many new products to meet the needs of the ever-changing market.
