Overall Appearance and Structure
1. Assembly Form: The two hoses are arranged side-by-side in a U-shape. The black hoses contrast sharply with the red and white connectors, reating a clean and uniform visual appearance.
2. Material and Craftsmanship: The main body of the excavator diesel pipe is a black, oil-resistant rubber hose with a smooth surface and a certain thickness, possessing high-temperature resistance and oil corrosion resistance. The connection points at both ends use metal rigid pipe transitions to enhance structural strength.
Connector Features (Key Identification Point)
1. Quick-Connect Design: Both ends of the hoses are equipped with red plastic quick-connect connectors (commonly known as "red-head quick-connects"), a prominent identifier for this type of accessory.
2. Snap-in and Sealing: The red connector base features a silver metal snap-in ring to secure the hose to the connector body, ensuring a tight, leak-free connection after installation. This is a standard original equipment manufacturer (OEM) accessory.
Product Advantages
1. Easy Installation: The quick-connect design eliminates the complex installation steps of traditional screws or clamps, allowing for rapid insertion and removal during maintenance.
2. High Durability: Designed for the high temperatures and frequent vibrations of excavator operation outdoors, both the hose and connector are reinforced for wear resistance, resulting in a long service life.
Applicable Scenarios and Functions
1. Compatible Models: The excavator diesel pipe is primarily compatible with mainstream excavator models such as Komatsu (PC200-8/PC200-7 series), and is also widely used in equipment with Cummins QSB5.9 engines.
2. Core Function: As a crucial fuel delivery line in the engine's fuel system, it is responsible for pressurizing and delivering fuel from the fuel tank to the engine injection system, or for circulating engine oil/hydraulic oil, ensuring the core of equipment power output.
