Perfect Circle Valve Stem Oil Seal Set

The Perfect Circle Valve Stem Oil Seal Set is engineered to control the amount of oil that passes down the valve stem and into the combustion chamber or exhaust port. Each valve stem seal set, also called a valve seal kit, helps reduce oil consumption, limit blue exhaust smoke, and protect engine performance during a rebuild or cylinder head service.

Key Features:

• Designed to meter oil on the valve stem while keeping oil out of the combustion chamber and exhaust
• Helps reduce oil burning and exhaust smoke caused by worn or hardened seals
• Made from durable, heat- and oil-resistant elastomer materials built for the high temperatures of engine operation
• Precision-molded sealing lips for consistent contact with the valve stem
• Offered in multiple application-specific configurations, including intake and exhaust seal sets
• From Perfect Circle, a long-established engine sealing and gasket brand

Replacing worn valve stem oil seals during an engine overhaul or cylinder head rebuild helps restore proper sealing, maintain oil control, and support long engine life. Select the correct part number for your engine from the available variants.
