Import Bascolin Common Rail Nozzle Dlla157p715 — Buy in wholesale FOB from Supplier in China

The Bascolin Common Rail Nozzle DLLA157P715 is a precision diesel fuel injector component engineered for high-pressure common rail fuel injection systems. Manufactured by China Balin Power Co., Ltd. in Putian, Fujian Province, this nozzle is constructed from high-grade tool steel with a tungsten carbide needle tip, a material pairing selected for wear resistance and sustained performance under extreme injection pressures. The DLLA157P715 designation follows Bosch standard nomenclature, where DLLA denotes a two-spring nozzle with a cylindrical spray hole, 157 indicates the spray angle in degrees, and P715 is the specific variant code.

Common rail nozzles of this type typically operate at injection pressures exceeding 1,800 bar, demanding micron-level manufacturing tolerances on the needle guide and seat regions. The tungsten carbide needle tip provides exceptional hardness (typical HRA 89-92) and resistance to cavitation erosion, which is the primary failure mode in high-cycle diesel injection. Standard manufacturing tolerances for the needle-to-body clearance range from 1.5 to 3.0 micrometres, ensuring hydraulic sealing without sticking. The spray hole diameter, typically 0.12-0.20 mm for this nozzle family, is finished by abrasive flow machining to achieve consistent flow coefficients.

This nozzle suits commercial vehicles, heavy-duty diesel engines, and industrial machinery where precise fuel atomisation directly impacts combustion efficiency and emissions compliance. Buyers include diesel engine rebuilders, fuel injection workshops, and aftermarket parts distributors serving the commercial vehicle sector. Importing from China Balin Power Co., Ltd. requires confirmation of exact MOQ, lead time, and whether the unit is supplied as a bare nozzle or with calibration data. The company lists additional common rail variants including DLLA150P1666, DLLA155P1674, and DLLA148P826, suggesting capability across multiple engine platforms.

China Balin Power Co., Ltd. operates from Hualin Industrial Zone in Putian, Fujian Province, China (postal code 351100). The company holds a harbor trust tier, which represents a baseline verification level on the platform. Notably, the supplier displays a 0.00% response rate with zero average response hours recorded, indicating no engagement data is currently available. This absence of response metrics is a material consideration for buyers evaluating communication reliability.

The company's stated specialisation covers the full spectrum of fuel injection components: head rotors, injector nozzles, common rail nozzles, plungers, delivery valves, common rail valves, control valves, and repair kits. Their product portfolio references dozens of active part numbers including DLLA157P715, DLLA150P1023, and DLLA158P1092, suggesting broad coverage of Bosch-type common rail and legacy pump-line-nozzle applications. No information is provided on company history, headcount, annual revenue, factory floor space, or specific OEM approvals. Buyers should independently verify ISO 9001 or IATF 16949 certification status, as well as any claimed OEM relationships, directly with the supplier before placing orders.
