Piston Ring Sets
CTP Piston Rings are technically optimized with:
- Advanced surface finish utilizing chrome plating, gas nitriding, spray coating and ceramic coating
- Superior base material such as gray cast iron, ductile cast iron and stainless steel
- High precision machining
The benefits:
- Excellent sealing performance will dramatically reduce blow-by gas and oil consumption.
- High anti-wear and breakage performance will assure you a longer part-life span.
