Valve stem seals are produced from high performance materials designed to extend lifetime and reduce wear. They are supplied in a variety of geometries to satisfy different assembly needs. Different valve stem seal types are also available to match customers’ application requirements. TECHNICAL FEATURES Oil lip Controls oil leakage through the seal and the valve guide. Step lip The not continuous rubber umps below the oil-lip give robustness to the design. Boot geometry Increases resistance against gas-lip bending with back-pressure and valve stem insertion, ensuring good flexibility to gas-lip. Gas lip Double lips allow lubrication against high back pressure and allow oil lips to operate in a stable environment. Flange (optional) Integrated spring washers are normally fitted separately MATERIALS Valve stem seals are typically made from high-quality elastomeric (rubber) materials, often reinforced with a metal spring or frame for structural integrity and consistent sealing force. Nitrile Butadiene Rubber (NBR): A common and cost-effective material. It has good oil and fuel resistance and can withstand temperatures typically between -40°F to 226°F (-40°C to 108°C). Polyacrylate (ACM): Offers better heat resistance than NBR. Fluoroelastomer (FKM/Viton): This is a premium material known for its excellent resistance to high temperatures (up to 450°F / 232°C or more), chemicals, oils, and wear. Viton seals are often preferred for modern, hotter-running engines. Silicone: Offers good high-temperature resistance but might have less wear resistance than Viton in some applications. PTFE (Teflon): Sometimes used for its low friction and chemical resistance, often in specific designs. The specific material chosen for an OEM valve stem seal like 09273-07005 is critical to its performance and lifespan, especially considering the harsh environment inside an engine (high temperatures, oil, fuel, and exhaust gases). You can contact us to customize various seals. Valve Stem Seal Section Consequences of inadequate oil flow Increased valve-train wear rate Premature valve-train failure Increased valve train noise Higher local temperatures Consequences of excessive oil flow High oil consumption Lower engine efficiency Poor catalyst performance Valve stem seals provide blow by control, eliminating the passage of exhaust gases through the seal. That is essential because inadequate control can cause: Insufficient lubrication Engine oil contamination VSS damage Engine power loss By installing Valve Stem Seals, customers can help to ensure that their engines will benefit from: Increased efficiency Consistant performance Reduced oil consumption Optimised catalyst performance Extende
