Import Diesel Fuel Pump Plunger Bosch 2455 022 — Buy in Bulk from Supplier in China

The Diesel Fuel Pump Plunger BOSCH 2455 022 is a precision component for Bosch PE12P-series injection pumps, matching the Dz-B455 0222 stamping code. It has a nominal diameter of 8.2 mm and a length of approximately 60 mm, designed for high-pressure fuel delivery in commercial diesel engines. This part replaces original Bosch units in vehicles using the PE12P110A320LS3820 pump model.

Manufactured from hardened carbon steel with a surface hardness of 60-64 HRC, it meets typical industry standards for durability under cyclic loading. The plunger is ground to a surface finish of Ra ≤ 0.2 μm and maintains a concentricity tolerance of 0.003 mm. Unlike some aftermarket versions, this part is not chrome-plated; the base material is treated for wear resistance. Variants in this line include the 2455 0022, 0122, and 0342 for different pump configurations.

This component is primarily purchased by diesel repair shops servicing MAN, Mercedes-Benz, Renault, Volvo, and Iveco trucks and buses. Buyers often require it for rebuilding PE12P-series pumps in Euro III and Euro IV compliant engines. Packaging is in individual sealed blister packs with part identification.
