In the world of automotive parts, size is not the only criterion for measuring value. XTSEAO 7*9*14.7/11.8mm NBR/FKM high-temperature weather resistant automotive oil seal, although compact, contains powerful sealing force, specially designed for high demand and high temperature automotive and industrial equipment.
Adopting a composite formula of NBR (nitrile rubber) and FKM (fluororubber), NBR provides excellent oil resistance and elasticity at room temperature, while FKM exhibits outstanding heat resistance, oxidation resistance, and chemical resistance in high temperature or corrosive media environments. Regardless of extreme cold or heat, it can maintain excellent sealing effect.Stable operation over a wide temperature range
7*9*14.7/11.8mm Valve Stem Seal High-Temperature Resistant Engine Valve Oil Seal
Precision Size: Standard dimensions 7914.7/11.8mm for perfect fit with various engine valve stems and guides, ensuring zero play or misalignment.
Durable Construction: Made of high-quality rubber (FKM/NBR) with metal shell and stainless steel garter spring, offering excellent resistance to heat, oil, wear and aging.
Oil Control & Sealing: Prevents excessive oil from entering the combustion chamber while maintaining proper lubrication for valve stems, reducing carbon buildup and oil consumption.
Reliable Performance: Stable sealing under high-speed reciprocating motion, effectively extending engine service life and reducing emissions.
These valve stem seals are critical components for internal combustion engines, designed to regulate lubrication and prevent oil leakage between valve stems and guides. With integrated molding technology, the rubber lip and metal shell are firmly bonded, providing superior durability and reliability. Ideal for gasoline and diesel engine maintenance, they serve as a reliable replacement for OE parts.
