The FG007Y003002+207/1 Composite Sealing Washer is a precision-engineered fastening component that provides reliable sealing under bolt heads and nuts, preventing fluid leakage and contamination ingress. As a trusted provider of genuine Sinotruk Homan parts, we have developed this composite washer to meet the exacting sealing requirements of SINOTRUK Homan heavy-duty trucks.
The FG007Y003002+207/1 features a unique metal-rubber bonded construction that combines the strength of a steel core with the conformability of a nitrile sealing lip, delivering superior compression-set resistance and leak-tight performance even under fluctuating temperatures and pressures.
With its optimized inner diameter and flat sealing face, this washer ensures consistent clamp load and effective sealing for critical fluid connections, including oil pan drain plugs, transmission filler ports, and hydraulic system fittings.
OEM direct replacement • Metal-rubber composite • Resists extrusion and cold flow
The FG007Y003002+207/1 composite sealing washer is designed to replace conventional copper or aluminum crush washers, offering superior reusability and sealing reliability.
Its bonded elastomer layer provides a conformable sealing surface that compensates for minor surface imperfections on the bolt head or housing, while the steel core maintains structural integrity and prevents over-compression.
This design ensures a leak-free seal for drain plugs, filler plugs, and other threaded connections that require a durable, vibration-resistant sealing solution.
Engineered specifically for SINOTRUK Homan engines and drivetrains, the FG007Y003002+207/1 is dimensionally matched to M8 fasteners and provides consistent torque retention. Its resistance to oil, coolant, and hydraulic fluids makes it a versatile choice for a wide range of fluid systems.
The FG007Y003002+207/1 composite sealing washer is primarily designed for SINOTRUK Homan trucks, including Howo A7, T7H, and Homan series models, where M8 fasteners are common in oil pan drain plugs, engine oil cooler fittings, and transmission fill plugs.
Its universal M8 size also makes it suitable for many other heavy-duty vehicles, agricultural equipment, and industrial machinery that use similar fastening systems.
This washer is ideal for applications requiring a robust, reusable seal that withstands thermal cycling and vibration. Whether used in engine oil drain plugs, hydraulic tank breathers, or fuel filter housings, the FG007Y003002+207/1 provides a dependable sealing solution that minimizes the risk of leaks and fluid loss, contributing to overall system reliability and uptime.
Installing the FG007Y003002+207/1 is straightforward. Clean the mating surfaces on the bolt head and housing to remove any old sealant, debris, or corrosion.
Place the washer onto the fastener with the rubber sealing face oriented toward the fluid side (typically facing the bolt head or nut). Tighten the fastener to the manufacturer’s recommended torque specification.
The bonded rubber will compress to form a conformable seal, while the steel core limits further compression to prevent over-tightening damage.
For maintenance, inspect the FG007Y003002+207/1 during each fluid change. If the rubber shows signs of cracking, hardening, or excessive deformation, replace it.
Under normal conditions, this washer can be reused several times, but always verify its sealing condition after removal. Reusing a damaged washer can lead to leaks and fluid loss, so replacement is recommended if any doubt exists.
Every FG007Y003002+207/1 composite sealing washer is produced under strict ISO 9001 quality management systems. The bonding process is carefully controlled to ensure uniform adhesion between the rubber and the steel core, preventing separation during installation or thermal cycling.
Each batch is sampled for dimensional accuracy, rubber hardness, and compression set resistance, guaranteeing that the washers meet the required performance criteria.
We also perform leak tests on representative samples using pressurized oil at elevated temperatures to simulate real-world operating conditions. These tests confirm that the FG007Y003002+207/1 maintains a leak-tight seal throughout its service life.
With this commitment to quality, you can trust that each washer delivers the reliability and durability demanded by SINOTRUK Homan trucks.
The FG007Y003002+207/1 composite sealing washer is a small but indispensable component that plays a vital role in preventing fluid leaks and maintaining system cleanliness.
Its advanced metal-rubber bonded construction offers superior sealing performance compared to conventional crush washers, providing a longer service life and reducing the risk of costly fluid loss.
By choosing this washer, you are investing in a reliable, reusable sealing solution that enhances the overall durability of your SINOTRUK Homan truck.
Fleet operators will appreciate the reduction in maintenance time and the decreased likelihood of leak-related failures. Owner-operators will gain peace of mind knowing that critical fluid connections are properly sealed, protecting the engine and driveline from premature wear.
