| | Main Products | | Piston Rings
Piston Rings that control lubrication oil are an important functional component requiring high precision and durability since they are used in parts moving at great speed.
Cylinder Liners
With the recent demands for fuel efficiency, higher performance, and lighter weight engine, there is a growing trend for improving cooling performance, reducing clearance between cylinder, and using aluminum blocks, Consequently, TPRV's is striving to improve adherence to the aluminum block by applying centrifugal casting method to make lines thinner, and thereby achive lower costs.
Valve seats
For materials used in production of sintered alloy valve seats, TPR breaks down particles using our proprietary special alloy powder. Featuring an excellent balance of heat resistance, wear-resistance, and compatibility with valves indispensable for valve seats, TPRV provides sintered alloy products that are compatible with all engines, including diesel, gasoline, and gas for either two or four wheel vehicles.
Valve guides
Valve guides support the stem of inlet and exhaust valves, keeps valve stabilization and helps to conduct the heat of valve to the cylinder head, durability and high precision are needed. Our Sintered material valve guides are excellent in wear resistance, heat resistance and mechanical properties, adopted with number of gasoline engines and diesel engines.
