OEM YC209-B122141PL The oil seal 122×141 is a precision component designed to retain lubricants and exclude contaminants in rotating shaft applications, such as transmissions, axles, and engines. The genuine SINOTRUK HOWO YC209-B122141PL Oil Seal 122X141 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 oil seal is crafted with high-strength, heat-resistant materials to endure harsh, high-pressure conditions in truck drivelines—effectively protecting bearings and gears from premature wear and ensuring reliable operation even during heavy-load or long-distance operations.
The YC209-B122141PL seal is molded from premium elastomers, chosen for excellent resistance to oil, heat, and wear.
The sealing lip is precision-molded and often features a garter spring to maintain constant radial force against the shaft, ensuring a leak-proof seal.
Manufactured to precise tolerances for a perfect interference fit in the housing and on the shaft, preventing leaks and extrusion.
Designed to remain flexible and effective from -40°C to +120°C, ensuring reliable sealing in all climates.

The oil seal may be a small component, but it plays a monumental role in maintaining lubricant levels and excluding contaminants. A failed YC209-B122141PL seal leads to oil leaks, contamination, and rapid wear of expensive bearings and gears. The genuine SINOTRUK HOWO seal is crafted with high-strength, heat-resistant materials to endure harsh conditions, ensuring lubricant stays where it belongs and components last.
The YC209-B122141PL seal is produced using high-precision injection molding. The sealing lip is formed to a sharp, defect-free edge, and the garter spring is accurately positioned.
Every batch of Sinotruk Howo Parts goes through strict testing against international standards (e.g., ISO, CE) and Sinotruk’s original specs. Seals are sample-tested for lip integrity, material hardness, and leak-proof performance.
The development of the YC209-B122141PL Oil Seal 122X141 focused on providing a reliable barrier against fluid loss under all operating conditions. These seals are subjected to continuous shaft rotation, temperature fluctuations, and chemical attack from lubricants. A leaking seal can cause expensive damage and downtime. This genuine component is engineered to maintain its sealing force and material integrity for hundreds of thousands of kilometers.
The material formulation of the YC209-B122141PL is critical. High-quality nitrile (NBR) or fluorocarbon (FKM) compounds are chosen for their resistance to specific lubricants and temperatures. The sealing lip is designed with a precise interference angle, and the garter spring provides constant radial force to compensate for minor shaft wear and runout.
Quality control for the YC209-B122141PL is exhaustive. In addition to 100% visual inspection of the sealing lip, sample seals are tested for hardness, tensile strength, and are subjected to dynamic test rigs that simulate shaft speed and oil temperature to verify long-term sealing performance. Only components that pass all these rigorous checks are approved for shipment as genuine Sinotruk Howo parts.
A failing oil seal can cause a range of issues. Symptoms include visible oil leaks under the truck, low fluid levels, contamination of brakes or other components, and eventual bearing or gear failure. During regular maintenance, seals should be inspected for leaks. If a leak is detected, immediate replacement with a genuine YC209-B122141PL seal is essential to prevent further damage.
Installation requires care. The old seal is carefully removed without damaging the housing or shaft. The new YC209-B122141PL seal is lubricated on the lip and pressed squarely into the bore using a suitable driver. The shaft is checked for burrs or wear before installation. Their user-friendly design, based on OEM specifications, helps experienced technicians perform the replacement efficiently.
Field performance of the YC209-B122141PL seal has proven its exceptional reliability. In a study of over 200 Howo trucks in long-haul service, genuine seals showed no leakage within 500,000 km when properly installed. This reliability translates directly to reduced fluid consumption, lower maintenance costs, and extended drivetrain life for fleet operators.
For parts managers, the YC209-B122141PL oil seals are available individually or in multi-packs, each with a lot traceability label. Bulk orders (20+ units) receive additional packaging discounts and priority handling. The seals are packaged in sealed bags to prevent contamination and damage during transit.
Warranty and support for the YC209-B122141PL 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.
