Import Diesel Plunger Barrel 2 418 455 145 — Buy in Bulk from Supplier in China

The Diesel Plunger Barrel 2 418 455 145 is a precision component designed for high-pressure diesel fuel injection systems, specifically compatible with Bosch and similar inline pump designs. It features an inner bore diameter of 7.0 mm with a surface finish of Ra 0.1 micron, matching the dimensional tolerances of original equipment manufacturers. The barrel is manufactured from hardened chrome-molybdenum steel, heat-treated to achieve a core hardness of 58-62 HRC, ensuring durability under continuous high-pressure cycling.

This component is typically used in medium-duty commercial diesel engines and agricultural equipment. The material composition conforms to standard DIN 1.7225 or equivalent, and the surface is ground and lapped to maintain tight clearance with the plunger, usually within 1.5 to 2.5 microns. Typical industry tolerances for bore roundness are ±0.5 microns, and the barrel length is 85.5 mm ±0.1 mm. Surface hardness and microstructure are verified by metallurgical analysis, though no third-party certification is stated by the supplier.

Buyers commonly source this part for repair of Perkins, Deutz, and Yanmar engines. It is sold in single-unit quantities with bulk discounts available upon request. Packaging is in anti-rust paper with individual plastic sleeves, and export shipments are typically palletized in cartons. Lead time is not specified, but the supplier claims quick delivery. Buyers should confirm compatibility with their pump model before ordering, as variations exist even within the same part number family.

Chen Chen Diesel Parts Plant operates from Fuzhou, Fujian Province, China, and specializes in manufacturing diesel fuel injection components including plungers, barrels, nozzles, and delivery valves. The supplier is listed as an imported tier with harbor trust status, indicating basic compliance with export documentation standards. There is no public information on years in business, workforce size, or revenue. The supplier does not list any certifications such as ISO or IATF, nor does it claim direct OEM supply relationships.

The supplier's website description emphasizes quality control and global exports but provides no verifiable details on testing protocols, inspection equipment, or traceability systems. Response rate and average response time are recorded as zero, suggesting limited buyer communication capability. Buyers should treat this as a manufacturer of replacement parts rather than an original equipment supplier, and validate part compatibility through physical measurement or pump model cross-reference before large orders.
