Elring Valve Stem Seal - ACM Polyacrylate

Elring valve stem seals made from ACM polyacrylate are engine valve stem oil seals. They control the amount of oil that passes down the valve stem into the combustion chamber and the exhaust port. Good control helps limit oil consumption, reduce smoke and emissions, and protect the engine over the long term.

Key Features:

• ACM polyacrylate elastomer: This material resists hot engine oil and heat better than standard nitrile rubber. It is a common choice for valve stem seals in modern engines.
• Controlled oil metering: The sealing lip lets enough oil through to lubricate the valve stem and guide. It blocks excess oil from reaching the combustion chamber.
• Dependable sealing: The seals are designed to hold their shape and sealing force over many heat cycles.
• Quality from Elring: Elring is a well-known German maker of gaskets, seals and sealing systems. It supplies both the OEM and aftermarket markets.

Worn or hardened valve stem seals often cause blue smoke at startup, higher oil consumption and fouled spark plugs. Replacing them during an engine rebuild or cylinder head service helps restore proper oil control. Each part number in this product line is a separate item.
