Fuel Line O-Ring - DD13 GHG17
Detroit Diesel

This fuel line O-ring is a precision-engineered sealing component designed specifically for DD13 engines operating under GHG17 regulations. Crafted from fluorocarbon elastomer, it provides excellent chemical resistance and thermal stability, ensuring a tight seal between fuel line connections. Its dimensions—inner diameter of 12.42 mm, outer diameter of 15.98 mm, and a cross-sectional diameter of 1.78 mm—are tailored to fit seamlessly into the fuel delivery system. Proper sealing prevents leaks that could lead to fuel wastage or potential fire hazards, while also maintaining consistent fuel pressure for reliable engine operation. The black color of the elastomer indicates its suitability for high-temperature environments encountered in diesel fuel systems. Installing quality O-rings like this one is essential for maintaining fuel system integrity and ensuring compliant emissions performance. Source One Parts Center provides this part as part of their commitment to reliable fuel system maintenance for heavy-duty applications.
