Fuel Sealing Washers xinglangjc 8 to 14mm Banjo Bolt for Dodge Cummins

Description

Product Overview

The xinglangjc fuel sealing washers are precision‑engineered components designed to fit the Banjo bolt connections commonly found in Dodge Cummins diesel engines. Each washer is manufactured from a high‑grade corrosion resistant alloy that balances flexibility with strength, allowing it to maintain a consistent seal even as temperature and pressure fluctuate during engine operation. The product is supplied in a convenient 40‑piece pack, covering a range of diameters from 8mm to 14mm, which matches the original part numbers 3918188, 4934278, 3963983, and 3963988. This ensures a direct, drop‑in replacement without the need for additional modifications or adapters.

Dimensions are carefully controlled to meet the specifications required for the fuel system of 5.9L and 6.7L Cummins engines. The washers feature a slightly tapered profile that promotes even distribution of pressure across the sealing surface, reducing the risk of localized wear and extending the service life of both the bolt and the surrounding fuel line. The material composition provides excellent resistance to fuel, oil, and coolant exposure, preventing degradation that could otherwise lead to leaks or engine damage.

Usage

These sealing washers are intended for use in heavy‑duty diesel applications where reliable fuel delivery is critical. Installers will typically encounter them during routine maintenance, fuel line replacement, or when addressing a fuel leak in the Banjo bolt area. The washers are compatible with both 12‑volt and 24‑volt fuel system configurations, making them suitable for a wide range of Dodge Cummins models, including trucks, SUVs, and off‑road equipment.

During installation, the washer is placed between the hollow bolt head and the fuel pipe flange. When the bolt is torqued to the manufacturer’s specifications, the washer compresses slightly, creating a seal that adapts to pressure changes. This self‑adjusting capability helps prevent fuel loss, protects engine components from contamination, and reduces the likelihood of costly downtime. The product is also ideal for aftermarket upgrades where enhanced sealing performance is desired.

Because the washers are supplied in a range of sizes, technicians can select the exact diameter required for a given application, ensuring a perfect fit and eliminating the need for custom machining. The robust construction also means the washers can withstand repeated removal and re‑installation, a common scenario in diagnostic or repair work.
