• After high temperature tempering, the elastic attenuation rate of piston ring is less than 5%/100 thousand kilometers, and it can still maintain good sealing and oil scraping effect after long-term use.
• With thin design, the weight of single piston ring is reduced by 15% compared with traditional products, which reduces the reciprocating inertia force of piston and improves the response speed of engine.
• The clearance with the cylinder wall is accurate, which ensures the sealing effect and avoids abnormal wear.
• When the piston ring is started at a low temperature of-40℃, it can still maintain good elasticity and avoid fracture or poor sealing caused by low temperature embrittlement.
• Easy installation and positioning: the ring end is provided with clear installation marks and positioning gaps to avoid installation errors, which can be easily operated by novices and reduce maintenance costs.
