NOK 49442345 Valve Stem Seal

The NOK 49442345 is a precision-engineered valve stem seal designed to provide critical oil control in internal combustion engines. This seal is installed on the valve guide to regulate the precise amount of oil needed to lubricate the valve stem while preventing excess oil from entering the combustion chamber.

Key Features:

• Precision oil metering design controls lubrication to valve stem and guide interface
• Prevents oil consumption and reduces harmful engine emissions
• High-temperature resistant construction withstands extreme engine operating conditions
• Self-tightening spring design maintains consistent seal pressure throughout service life
• Premium fluorine rubber (FKM) material resists aggressive oils and high temperatures
• Prevents carbon deposits that can cause valve seat damage and premature wear

NOK valve stem seals are manufactured to exacting OEM specifications using advanced materials and quality control processes. Proper valve stem sealing is essential for maintaining optimal engine performance, fuel efficiency, and reducing oil consumption. Worn or damaged valve stem seals can lead to increased emissions, blue smoke from exhaust, and excessive oil use.
