Import Diesel Plunger — Buy in Bulk from Supplier in China

The Diesel Plunger offered by Rader Auto Parts Group is a replacement component listed with over 80 distinct part numbers, including models such as 090150-0030, 131101-1820, and 105700-51100. These correspond to specific injection pump applications, primarily in European and Japanese diesel engines. Each plunger is machined to match OEM specifications for diameter, length, and taper, with variations based on pump type and engine model.

These components are typically produced from high-carbon alloy steel, with surface treatments including nitriding or chrome plating to enhance durability. The material selection aligns with common industry standards such as DIN 1.2842 or SAE 52100. Plunger lengths range from 80 mm to 110 mm depending on application, and diameters vary between 6.5 mm and 7.5 mm. These are not generic parts but model-specific replacements.

Buyers typically source these plungers for repair facilities servicing trucks, tractors, and marine diesel engines. The supplier’s extensive part list suggests broad compatibility across brands like Bosch, Zexel, and Denso. Packaging is likely bulk carton with internal dividers. Minimum order quantities and lead times are not specified and must be confirmed. Trade terms are not stated and require direct inquiry.

Rader Auto Parts Group is based in the Mawei Industry & Economic Development Area in Fuzhou, Fujian Province, China. The supplier is classified as imported with harbor trust status, indicating verified export activity. The listing does not disclose years in business, workforce size, certifications, or production capacity. No response rate or average response time is provided, suggesting limited buyer interaction infrastructure.

The company appears to specialize in diesel fuel system components, particularly plunger replacements for a broad selection of injection pumps. The extensive part number list implies a focus on aftermarket compatibility rather than original equipment production. There is no mention of in-house testing, heat treatment, or quality control processes. Buyers should treat this as a distributor or manufacturer with broad catalog coverage but limited public operational details.
