Valve Seal TOYOTA SCION FR-S 4U-GSE / Subaru BRZ ST-VS-T5.5E

Viton valve seals with reduced outside diameter are ideal for those who use double valve springs or may have problems with valve spring play or simply need to install new valve seals due to worn components. (Viton) seals have a temperature range of -5 ° to 450 ° F, making them one of the best high temperature seals available. Viton has good flexibility like nitrile which means it can handle some runout between the valve stem and the guide. It is also considered a more durable material than silicone. Viton also has better wear resistance than most other sealing materials, making it a good choice for applications where long-term durability is a must.Fits: TOYOTA SCION FR-S 4U-GSE / Subaru BRZ a reduced outside diameter are ideal for those that use double valve springs or may have problems with valve spring loose or simply have to install new valve seals due to worn parts.Seals (Viton) have a temperature range of -5 ° to 450 ° F , which makes them one of the best available high temperature seals. Viton has good flexibility, like nitrile, which means that it can handle some beating between the valve stem and the guide. It is also considered a more durable material than silicone. Viton also has better wear resistance than most other sealing materials, which makes it a good choice for applications where long-term durability is a must.Fits: TOYOTA SCION FR-S 4U-GSE / Subaru BRZReferences: Fits exhaust valves
