Valve stem Seal (Diesel)

Product Description

The Valve Stem Seal is an essential component for 4-stroke diesel engines and is available in two variants designed specifically for 7 HP and 9 HP models. Its primary function is to control oil flow to the valve stem, helping prevent excessive oil consumption, coke build up, and emissions while ensuring proper valve lubrication. These seals are manufactured from high-quality FKM/Viton rubber for enhanced heat resistance, durability, and chemical stability, meeting the demanding conditions of agricultural and industrial engines. Non-integrated and high-pressure designs are available, tailored to specific engine requirements, providing reliable performance whether installed on the intake or exhaust valve guides.

Variant 1: For 7 HP Diesel Engine

• Compatible with 7 HP diesel engines, including models like 178F commonly found in power tillers and cultivators.
• Made from heat-resistant FKM/Viton rubber for long service life in high-temperature environments.
• Non-integrated design for standard oil metering to the valve stem, preventing excess oil burn and maintaining clean valve operation.
• Provides an ideal seal to keep oil out of the combustion chamber and reduce emission and fouling.
• Easy to install, suitable for both maintenance and engine rebuilds.

Variant 2: For 9 HP Diesel Engine

• Designed for 9 HP diesel engines, including the 186F model, used in power tillers, cultivators, and generators.
• High-pressure steam seal option available for engines with turbochargers or exhaust brake systems, with additional sealing lip for maximum pressure resistance.
• Premium rubber construction resists aggressive oils and combustion residues, ensuring reliable long-term function.
• Integrated or non-integrated design tailored to fit the specific requirements of 9 HP engines for optimal oil metering.
• Helps maintain engine compression, proper lubrication, and reduces maintenance frequency.
