Namura Technologies PWC Piston Ring Set

Namura Technologies piston rings are made for personal watercraft (PWC) engine rebuilds. They help restore compression and cylinder sealing during a top-end refresh. This piston ring set line is for riders and shops who want dependable replacement rings, also called compression rings or piston ring kits, for Yamaha PWC engines.

Key Features:

• Built to OEM-style specifications: Namura makes its piston rings to exacting OEM specifications. Precision tolerances support good compression and long service life.
• Several bore options: Rings are offered for different bore sizes, so you can match the set to your pistons and cylinders.
• Part of a full rebuild range: Namura also offers pistons, gaskets, connecting rods and bearings for PWC, MX, ATV and UTV riders. The rings pair easily with other top-end components.
• Restores engine performance: New rings are a cost-effective way to improve compression and seal the combustion chamber during a top-end rebuild.

Some Namura ring series are designed for specific piston series and are not interchangeable with OEM pistons or rings. Choose the individual part number that matches your engine's bore and piston type.
