Elring 731.021 Engine Timing Chain Tensioner Gasket

The Elring 731.021 is a precision-engineered timing chain tensioner gasket (also known as a timing chain tensioner seal) designed to provide a reliable, leak-free seal at the timing chain tensioner. A proper seal at this location is essential for maintaining correct oil pressure to the tensioner, which in turn keeps the timing chain properly tensioned and your engine's valve timing accurate.

• Engineered to reliably seal the timing chain tensioner and prevent oil leaks
• Manufactured from durable, heat-resistant materials built to withstand the extreme pressures found inside a modern engine
• Precision manufacturing ensures an accurate fit for confident installation
