OEM WG2210100004 The sealing washer may be a small component, but it plays a monumental role in preventing fluid leaks in critical truck systems—from engine oil drains to hydraulic connections. The genuine SINOTRUK HOWO WG2210100004 Sealing Washer is an OEM‑grade component engineered for a perfect fit and long‑term durability. As a vital element of the trusted Sinotruk howo parts family, this washer is crafted from high-strength, anti-corrosion materials to bear heavy loads, resist extreme pressure, and stand up to harsh weather—effectively sealing key connections like drain plugs and banjo bolts to prevent leaks and ensure reliable operation.
The WG2210100004 washer is manufactured from premium copper or aluminum alloy, annealed to the correct softness for optimal sealing without cracking.
When compressed, the soft metal deforms to fill microscopic imperfections in the mating surfaces, creating a reliable, long-lasting seal against oil, fuel, or coolant.
Inner and outer diameters are held to tight tolerances, ensuring a perfect fit on the bolt or plug and within the counterbore, preventing extrusion.
The material naturally resists corrosion from fluids and road salt, ensuring the washer can be removed without seizing, even after years of service.

A simple sealing washer is the final line of defense against fluid leaks at threaded connections. A failed or reused WG2210100004 washer can lead to oil drips, fuel leaks, or coolant loss, resulting in system failure, environmental damage, and safety hazards. The genuine SINOTRUK HOWO washer is crafted from high-strength, anti-corrosion materials to bear heavy loads, resist extreme pressure, and stand up to harsh weather, ensuring a perfect seal for the life of the connection.
The WG2210100004 washer is blanked from strip metal with precision tools. Edges are deburred, and the washer is annealed in a controlled atmosphere to achieve consistent softness.
Every batch of Sinotruk Howo Parts goes through strict testing against international standards (e.g., ISO, CE) and Sinotruk’s original specs. Washers are sample-tested for hardness and dimensional accuracy.
The development of the WG2210100004 Sealing Washer focused on providing a reliable and economical seal for critical fluid connections. These washers are subjected to extreme pressure and temperature cycles. A leaking washer can cause expensive fluid loss and downtime. This genuine component is engineered to deform precisely under specified torque, creating a perfect seal for the service interval.
The material and annealing of the WG2210100004 are critical. High-purity copper is chosen for its excellent corrosion resistance and ability to deform without work-hardening excessively. The annealing process softens the copper to the exact degree needed to flow into surface irregularities without cracking or extruding out of the joint.
Quality control for the WG2210100004 is exhaustive. In addition to 100% visual inspection, sample washers are tested for hardness on the Rockwell or Vickers scale. Dimensional checks ensure ID, OD, and thickness are within specification. Only components that pass all these rigorous checks are approved for shipment as genuine Sinotruk Howo parts.
A failing sealing washer can cause a range of issues. Symptoms include visible oil or fuel drips under the truck, a drop in fluid levels, or stains around fittings. During every oil change or component service, sealing washers on drain plugs and banjo bolts should be replaced. Never reuse a crush washer. If any leak is detected, immediate replacement with a genuine WG2210100004 washer is recommended.
Installation is simple but critical. The old washer is removed, and the mating surfaces are cleaned. The new WG2210100004 washer is placed on the bolt or plug, which is then inserted and torqued to specification. The soft metal crushes, forming the seal. Their user-friendly design simplifies replacement, helping technicians cut down on repair time and get Howo trucks back on the road faster.
Field performance of the WG2210100004 washer has proven its exceptional reliability. In countless Howo trucks, genuine washers provide leak-free sealing for the entire service interval when properly torqued. This reliability translates directly to reduced fluid loss and lower maintenance costs for fleet operators.
For parts managers, the WG2210100004 sealing washers are available in various pack quantities, from small packs of 10 to bulk boxes of 1000, each with lot traceability. Bulk orders receive additional packaging discounts and priority handling. The washers are packaged in sealed bags to prevent oxidation.
Warranty and support for the WG2210100004 are comprehensive. SINOTRUK HOWO provides a 2‑year warranty against manufacturing defects. Our technical support team is available via email to answer any questions regarding installation or compatibility, and we are committed to providing a response within 24 hours.
When ordering, always verify the required inner diameter for your application. The WG2210100004 is a common size for M12 and similar fittings, but confirming the correct ID ensures a perfect fit and optimal sealing performance.
In summary, the WG2210100004 Sealing Washer is a vital component for ensuring the leak-free operation of your SINOTRUK HOWO truck’s fluid systems. Its premium materials, precision manufacturing, and rigorous testing make it the preferred choice for critical seals. Trust the genuine WG2210100004 – it keeps your fluids where they belong.
Always replace sealing washers whenever a bolt or plug is removed. Never reuse a crush washer. Clean the mating surfaces thoroughly before installing a new WG2210100004 washer. Torque to specification to ensure proper crush and seal.
