The BY612600080275 Sealing Washer is used in numerous critical fluid connection points on a SHACMAN truck. Typical applications include sealing hydraulic hose and pipe fittings, sealing engine oil drain plugs and sensor ports, and sealing fuel line union nuts and coolant pipe connections.
Its primary function is to create a pressure-tight seal between a fastener (bolt or nut) and its mating surface, preventing the leakage of fluids under pressure. Unlike a standard flat washer, the BY612600080275 deforms to fill microscopic grooves and imperfections, creating a custom seal for that specific joint. It also helps distribute the clamping load to prevent damage to softer materials.
For maintenance teams, using the genuine BY612600080275 washer ensures a reliable, leak-free connection every time a fluid system is opened and reassembled. It is a small but vital component in preventing costly leaks and system contamination.
For operators, this washer contributes directly to a clean, dry undercarriage, consistent hydraulic performance, and the prevention of fluid loss that could lead to system failure or environmental spills. Its reliability is fundamental to the leak-free operation of all pressurized fluid systems.
1. Ensure the sealing surfaces on both the fastener and the component are clean, dry, and free from old sealant, burrs, or damage.
2. Place the new BY612600080275 sealing washer onto the bolt or stud, ensuring the sealing ring/rib side faces the component’s flange surface (usually).
3. Insert the fastener and hand-tighten until the washer makes contact with the sealing surface.
4. Using a calibrated torque wrench, tighten the fastener to the exact torque specification provided by SHACMAN for that specific application. Do not overtighten.
5. The correct torque will cause the washer to deform (crush) slightly, creating the seal. You may feel increased resistance as the washer deforms.
6. For critical hydraulic connections, it is good practice to cycle the system pressure and then re-check the torque after a short operational period.
7. Always replace the BY612600080275 washer with a new one anytime the connection is disassembled. Reusing a crushed washer will result in a leak.
• During routine inspections, check all connections using BY612600080275 washers for signs of weeping or fluid seepage.
• If a leak is detected, do not simply overtighten the bolt. This can damage the threads or flange. Instead, disassemble, clean, and install a new BY612600080275 washer, torquing correctly.
• Keep a stock of common-sized BY612600080275 washers in your maintenance kit. Using the correct OEM washer is faster and more reliable than applying liquid thread sealant.
• Store washers in a dry environment to prevent corrosion of the protective plating before use.
• When performing fluid changes (oil, coolant), always plan to have new sealing washers for the drain plugs and sensor ports.
• For fleet operations, include sealing washers in the standard parts list for common repair procedures to ensure technicians always have the correct part on hand.
Proper installation is key. The sealing action comes from controlled deformation under precise torque, not from extreme force. Always follow the manufacturer’s torque specifications.
