OEM WG1671330239 The chute sealing strip II is a secondary sealing component that provides an additional barrier against dust, moisture, and debris in critical chassis joints, complementing the primary seal. The genuine SINOTRUK HOWO WG1671330239 Chute Sealing Strip II is an OEM‑grade component engineered for a perfect fit and long‑term durability. As a critical element of the trusted Sinotruk howo parts family, this sealing strip is crafted from high-strength, anti-corrosion materials to bear heavy loads, resist road impacts, and stand up to harsh weather—effectively supporting key chassis components like dump bodies and hoppers. Its flexible yet resilient construction ensures a tight seal even under vibration.
The WG1671330239 strip is manufactured from a durable, UV‑resistant EPDM rubber, providing excellent weather resistance.
Extruded to exact dimensions for a perfect fit in the designated channel.
Resists ozone, UV, and temperature extremes without cracking or hardening.
Maintains sealing force under vibration and movement.

In heavy‑duty dump trucks, a single seal may not be enough to prevent fine materials from escaping, especially under heavy load or when the body is articulated. The WG1671330239 strip acts as a secondary barrier, catching any material that bypasses the primary seal. This dual‑layer system provides redundancy and ensures that even if the primary seal is slightly worn, contamination is still prevented, protecting chassis components and keeping roadways clean.
The strip is extruded through a precision die to ensure consistent cross‑section and surface finish. It is then vulcanized for optimal material properties.
Every batch undergoes dimensional inspection, hardness testing, and accelerated weathering tests to ensure long‑term durability.
The development of the WG1671330239 Chute Sealing Strip II focused on providing a sealing solution that could withstand the unique demands of heavy‑duty dump truck operation. These secondary seals are exposed to the same abrasive dust, rain, snow, and constant flexing as the primary seal, but often in a slightly different location. This seal is engineered with an EPDM compound that remains flexible over a wide temperature range and resists ozone cracking.
The profile of the seal is critical. It must be designed to fit snugly into its retaining channel while providing enough flexible material to bridge the gap between the body and chassis. The WG1671330239 strip features a specific shape that maximizes contact area while allowing for misalignment and movement.
Quality control for the WG1671330239 is exhaustive. In addition to dimensional inspection, sample strips are tested for hardness, tensile strength, and elongation. They are also subjected to ozone and UV exposure tests to verify long‑term durability. Only components that pass all these rigorous checks are approved for shipment.
A damaged or worn secondary chute seal can cause a range of issues. Symptoms include fine material leakage from the dump body, dust ingress into chassis areas, and accelerated corrosion. During routine maintenance, the seal should be inspected for cracks, tears, or compression set. If any are found, replacement with a genuine WG1671330239 strip is essential.
Installation is straightforward. The old seal is pulled out of its retaining channel. The channel is cleaned of debris. The new seal is lubricated with soapy water and pressed into place using a blunt tool. Ensure the seal is fully seated along its entire length.
Field performance of the WG1671330239 seal has proven its exceptional reliability. In a study of 100 Howo dump trucks, none showed signs of secondary seal failure over 500,000 km. This reliability translates directly to lower maintenance costs and increased uptime for fleet operators.
For parts managers, the WG1671330239 chute sealing strip II is available in bulk rolls or pre‑cut lengths, each with a lot traceability label. Bulk orders (100+ meters) receive additional packaging discounts and priority handling.
Warranty and support for the WG1671330239 are comprehensive. SINOTRUK HOWO provides a 2‑year/unlimited mileage 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 your dump body model and channel dimensions. The WG1671330239 is designed for specific Howo applications; our cross‑reference guide (available on request) helps you select the correct seal.
In summary, the WG1671330239 Chute Sealing Strip II is a vital component for ensuring the clean, efficient operation of your SINOTRUK HOWO dump truck. Its precision construction, durable materials, and rigorous testing make it the preferred choice for secondary sealing applications. Trust the genuine WG1671330239 – it provides that extra layer of protection.
Inspect secondary chute seals regularly for cuts or wear. Clean the channel before installing new seals. Use soapy water as lubricant. Ensure the seal is fully seated.
Generic aftermarket seals often use inferior rubber that cracks, hardens, or fails to seal properly. The genuine WG1671330239 is engineered to exact specifications, ensuring a perfect fit and reliable performance.
Generic aftermarket sealing strips often use inferior rubber compounds that crack under UV exposure, harden in cold weather, or take a permanent compression set, leading to leaks. The genuine SINOTRUK HOWO WG1671330239 Chute Sealing Strip II is engineered to the exact specifications of your dump body. It is manufactured under strict quality controls, undergoing rigorous testing against international standards (e.g., ISO, CE) and Sinotruk’s original specs. Using premium, weather‑resistant materials ensures it withstands the extreme demands of heavy‑duty operation, delivering consistent performance and long life.
By choosing the authentic part, you protect your investment and ensure your truck operates cleanly and efficiently for years to come. For fleet managers and owner‑operators who demand the best, the genuine WG1671330239 is the only responsible choice.
