Nippon Reinz Valve Stem Seal

Nippon Reinz valve stem seals are engine valve stem oil seals made to replace worn or hardened original seals. They control how much oil reaches the valve stem and guide. Replacing them helps reduce oil consumption, exhaust smoke, and valve train wear. They are also sold as valve guide seals or valve stem oil seals.

Key Features:

• Oil metering: A valve stem seal's main job is to let the right amount of oil reach the valve stem and guide. Reinz designs are evaluated on oil-metering test equipment to balance valve train durability, oil consumption, and emissions.
• Emissions protection: Proper oil control helps limit the oil and particulate build-up that can foul exhaust after-treatment components over time.
• Quality sealing materials: Reinz valve stem seals use fluoroelastomer compounds that are mixed in house and tested, followed by a controlled molding and assembly process.
• Application-specific designs: Each part number is made for a specific engine application, so choose the seal that matches your engine.

Nippon Reinz parts are part of the Reinz sealing family, known for gaskets and seals. They suit engine rebuilds, cylinder head service, and repairs for oil consumption or blue smoke on start-up.
