Diesel Plunger Barrel 2 418 425 995

The Diesel Plunger Barrel 2 418 425 995 is another key element of a diesel fuel injection system, bearing the part code 2 418 425 995. It is manufactured by Chen Chen Diesel Parts Plant in Fujian Province, China, and forms part of the plant’s second‑generation barrel series. Designed to guide the high‑pressure plunger during fuel delivery, this barrel integrates with the injector’s camshaft. Chen Chen lists the 2‑series alongside its wider range of diesel injection components for global markets.

Standard construction uses forged alloy steel that is heat‑treated to reach a typical hardness of 48‑52 HRC, aligning with common diesel‑engine standards. The bore diameter is controlled within a tolerance of ±0.025 mm, and the outer surface is finished to a Ra 1.0 µm roughness, both typical for reliable fuel flow. Production includes magnetic particle inspection and a final pressure test to verify sealing performance, reflecting usual industry practice. The supplier’s overview mentions strict quality checks but does not publish specific certification documents, which buyers should request.

This barrel is suited for medium‑speed diesel engines used in marine auxiliary power units and industrial generators. Purchasers are typically equipment manufacturers or large‑scale service providers that need traceable parts for maintenance contracts. While the supplier highlights prompt shipment, details such as minimum order quantity, incoterms and payment schedule must be clarified with Chen Chen.

Chen Chen Diesel Parts Plant operates from 35, Qixia Road, Gulou District, Fuzhou, Fujian Province, 350003, China. Classified as an imported tier with a harbor trust level, its recorded response rate is 0 percent, indicating that communication may not be immediate.
