Import Cng Injector Rail Fgf4 — Buy in Bulk from Supplier in China

The CNG injector rail FGF4 is a precision-engineered component designed for sequential CNG and LPG injection systems in internal combustion engines. It is rated for operating pressures up to 20 bar and features a single-piece aluminum alloy body with integrated fuel ports for five injectors. The unit weighs exactly 0.5 kg and is compatible with standard 6mm O-ring fuel line connections. This rail is built to maintain consistent fuel pressure across varying engine loads, ensuring stable combustion and reduced emissions.

The rail is manufactured using die-cast aluminum with an anodized finish to resist corrosion from compressed natural gas and condensation. Typical industry standards for such rails include SAE J1928 for pressure integrity and ISO 14230 for fuel system compatibility. While the listing does not specify material grade, standard aerospace-grade ADC12 aluminum is commonly used in comparable injector rails for its thermal stability and machinability. Packaging is standardized at 50 units per carton, with foam inserts to prevent vibration damage during transit.

This component is primarily purchased by aftermarket CNG conversion specialists, OEM vehicle modders, and fleet operators retrofitting diesel or gasoline vehicles to run on natural gas. Buyers typically require proof of pressure testing and dimensional tolerances before bulk procurement. Trade terms available include FOB Shanghai and CIF ports, with payment via T/T or L/C. Minimum order quantities are not stated in the listing and must be confirmed directly with the supplier.

Shangyu Tongli Fluid Control Co., Ltd. is based in Dongguan Town, Shangyu, Zhejiang, China, and operates as a manufacturer of fluid control components for alternative fuel systems. The listing confirms the supplier’s physical address and indicates a harbor-tier trust rating, suggesting verified export experience. There is no public data on company size, years in operation, or client list, and no certifications are claimed. The supplier responds to inquiries at a rate of 0.00%, indicating no recent buyer engagement on the platform.

This supplier specializes in fuel delivery components for CNG and LPG applications, with the FGF4 injector rail being one of its listed products. No claims are made regarding ISO certification, internal testing facilities, or R&D capacity. The absence of response metrics and certification details suggests a low-touch sourcing model. Buyers should treat this as a direct manufacturer without verified quality assurance systems unless confirmed in writing.
