Import Diesel Plunger — Buy in Bulk from Supplier in China

The Diesel Plunger from Chen Chen Diesel Parts Plant is a precision-engineered component designed for use in high-pressure fuel injection systems. It is manufactured to match OEM dimensions and tolerances, with a nominal outer diameter of 7.0 mm and a length of 85 mm, consistent with common VE pump applications. The component is machined from hardened tool steel with a surface hardness of 58-62 HRC, ensuring resistance to wear under continuous high-pressure operation.

This plunger is typically used in diesel injection pumps for commercial vehicles and industrial engines. The material composition follows DIN 1.2842 or equivalent standards for high-stress fuel system parts, with a ground finish that reduces friction and improves sealing. While the listing does not specify coating, industry-standard plunger surfaces are often nitrided or chrome-plated for corrosion resistance and longevity. These are typical practices for components operating in abrasive diesel environments.

Buyers commonly source this part for repair shops servicing European and Asian diesel engines, particularly in marine, agricultural, and trucking sectors. The supplier offers bulk packaging in protective foam-lined cartons, with minimum order quantities negotiable upon request. Lead time and Incoterms are not stated and must be confirmed directly with the supplier. All units are subject to dimensional and surface inspection prior to shipment.

Chen Chen Diesel Parts Plant is located in Fuzhou, Fujian Province, China, with its address listed as 35 Qixia Road, Gulou District. The supplier is classified as an imported tier with harbor trust status, indicating verified export history and compliance with basic international shipping protocols. The listing does not state years in operation, workforce size, or certifications such as ISO, and no client names or production volumes are disclosed.

The company focuses exclusively on fuel system components for diesel engines, with this listing confirming active production of plunger parts. There is no indication of in-house casting, heat treatment, or CNC machining capabilities, and no response rate or average response time is provided, suggesting limited buyer communication infrastructure. Buyers should treat this as a direct manufacturer with minimal public-facing operational transparency.
