The PISTON RING 4D32 stands as a premium component engineered for diesel engines, designed to deliver exceptional reliability and performance. As a key product from Guangzhou ShuangCheng Auto Parts Co., Ltd.—a China-based manufacturer with ISO 9001 certification—this piston ring is crafted to meet rigorous industry standards, ensuring seamless integration and long-term durability.
Piston rings are critical to engine functionality, and the PISTON RING 4D32 excels in two primary roles: as a compression ring and an oil ring. The compression ring works to maintain airtightness within the combustion chamber, preventing the leakage of combustible mixtures and maximizing engine efficiency. Meanwhile, the oil ring efficiently scrapes excess oil from the cylinder walls, regulating lubrication to avoid oil consumption issues and reducing wear on engine components.

Backed by a production capacity of 10,000 sets/year, this piston ring is manufactured using high-grade materials and advanced techniques, making it a trusted choice for both original equipment manufacturers (OEMs) and aftermarket replacements. Whether for routine maintenance or engine overhauls, the PISTON RING 4D32 offers consistent performance, supported by 24-hour after-sales service to address any queries or concerns promptly.
