Good To Know

Q: Can this gasket be reused after removal? A: No, exhaust valve gaskets are single-use, so fit a new one any time the valve is removed.

Q: What causes an exhaust valve gasket to fail? A: Heat cycling and age harden the material over time, which lets exhaust gas escape and usually calls for replacement.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
