Detroit Diesel Fuel Injector Lines Adapter Seal 

The Detroit Diesel Fuel Injector Lines Adapter Seal combines metal and rubber layers to create a secure sealing surface for DD15 injector-line interfaces. Its layered construction helps preserve sealing consistency in high-pressure regions where fuel pulses travel through narrow passages. Engines equipped with DD15 systems depend on seals that can maintain contact despite temperature gradients common in long-haul environments. This seal offers a stable interface that supports the injector line’s ability to deliver metered fuel without pressure irregularities. In systems requiring exact injector timing, the Detroit Diesel A4720780480 delivers exceptional sealing performance.
