Wholesale only · Full payment before shipment · Send your machine nameplate to confirm fitment
Description
The fuel system seal is a component used to prevent fuel leaks or seepage at the connection point between the exhaust manifold and the fuel system. It ensures a proper, secure seal, preventing fuel from escaping into the surrounding area and causing hazards such as fire or poor engine performance. It also provides an insulating layer to protect the fuel from overheating, reduce vibration or noise, or promote proper fuel flow within the system.
Attributes
Withstands the heat generated by the exhaust manifold.
Provides proper alignment and sealing.
Long-lasting and durable.
Applications
The fuel system seal is used to maintain a secure, leak-free connection between the exhaust manifold and fuel system components. Widely used in Cat® 3512, 3512E, 3608, C175-16, and C175-20 Engines (Piston), 3516E, C175-16, C175-20, and C18 Generator Sets, 785D, 789D, 793, 793D, 793F, 794, 795F, 796, 797, 797B, 797F, and 798 Trucks, PR43C Locomotive, SPF743 Pump Truck, and Cement Trucks.
