Import Caterpillar Injector Nozzle 387-9433 — Buy in Bulk from Supplier in China

The Caterpillar Injector Nozzle 387-9433 is a precision component designed for direct injection diesel engines, compatible with Caterpillar models such as 3304, 3306, D330, D333, and 1673. It features stamping numbers including 7S1059, 137-2500, and 10R0963, which correspond to specific engine configurations and performance requirements. This nozzle is part of a broader range of fuel injection parts that Diesel Injection Parts Plants supplies for heavy-duty applications.

Manufactured from high-grade alloy steel, the nozzle undergoes strict quality checks to ensure durability under high-pressure conditions typical in diesel engines. Typical industry standards for such nozzles include a pressure rating of 200-300 bar and a spray angle tolerance of ±2 degrees, ensuring optimal fuel atomisation. The nozzle’s design adheres to Caterpillar’s OEM specifications, with a standard thread size of M12x1.25 and a tip protrusion that matches the engine’s combustion chamber geometry.

This injector nozzle is primarily used in construction, agricultural, and marine diesel engines where reliability and precision are critical. Buyers typically include equipment manufacturers, repair workshops, and distributors sourcing OEM or aftermarket parts. Trade terms for such components often involve bulk packaging in cartons of 50-100 units, with lead times dependent on stock availability and customisation requirements.

Diesel Injection Parts Plants is based in Putian, Fujian Province, China, specialising in the production and supply of fuel injection components for diesel engines. The company operates from Longqiao Street, a region known for its concentration of automotive parts manufacturers, and focuses on serving both domestic and international markets with OEM and aftermarket solutions.

The supplier’s profile indicates a harbor trust tier, reflecting a baseline level of verification for export readiness. While the response rate and average response hours are currently unrecorded, the company’s product catalog includes a wide array of injector nozzles and related parts, such as those listed under Caterpillar-compatible codes. This positions them as a niche provider for buyers seeking specific, hard-to-find components for heavy machinery.
