29566019 Sealing and Gasket Package Allison spare parts

29566019 Sealing and Gasket Package Allison spare parts

The 29566019 sealing and gasket package is a complete set of accessories specifically designed for sealing and protecting Allison transmissions and various industrial and commercial vehicle equipment. It precisely matches the original equipment manufacturer (OEM) standards and is widely compatible with Allison transmissions and various commercial vehicles, construction machinery, and special vehicles. Its core function is to seal and protect critical components such as transmission housings, pipe interfaces, gearbox end covers, and hydraulic system connections. Through precise contact with the sealing surface, it prevents impurities such as oil, dust, and moisture from entering the equipment, while also preventing internal oil leakage. It is a core component combination that ensures equipment sealing performance and extends equipment lifespan, directly determining the reliability, safety, and economy of equipment operation.

Core technical parameters:

• Part number: 29566019
• Material Specifications: It adopts a combination of diverse high-end composite materials. The core gasket is made of 304 stainless steel strip with graphite filling layer. The seal is made of nano-grade silicon carbide filled polytetrafluoroethylene (PTFE) material. Some seals are made of nitrile rubber (NBR). It meets the corrosion resistance standard of GB/T 10125-2021. The temperature resistance of the graphite gasket can reach -220℃ to 550℃. The friction coefficient of the PTFE seal is as low as 0.08.
• Structure type: Complete set design, including metal spiral wound gaskets, PTFE gaskets, rubber sealing rings and other accessories of various specifications, to fit the sealing points of Allison gearboxes. The metal spiral wound gasket adopts a “V” shaped metal strip spiral winding structure and is fixed by spot welding at the end. The sealing components adopt an integrated molding design, and the sealing surface fits tightly without gaps, effectively preventing leakage and adapting to static and dynamic sealing scenarios.
• Dimensional parameters: The complete set includes various specifications, with the core gasket diameter ranging from 15mm to 80mm and the thickness from 2mm to 5mm. The inner diameter of the sealing element ranges from 10mm to 60mm, with dimensional tolerances ≤ ±0.02mm and sealing surface roughness Ra ≤ 1.6μm, conforming to DIN international standards. This ensures precise fit and tight contact with the equipment’s sealing points, with a compression rate of 18%-30% and a rebound rate ≥ 17%, guaranteeing long-term sealing stability.
• Compatible Models: Precisely compatible with Allison 1000/2000 series transmissions, suitable for various commercial vehicles, construction machinery, and special vehicles equipped with this series of transmissions, as well as other industrial equipment, hydraulic systems, and transmission sealing scenarios with corresponding sealing points.
• Protective performance: It has excellent leak-proof, corrosion-proof, dustproof and waterproof performance. The corrosion resistance level reaches the 72-hour salt spray test standard. It can effectively resist the erosion of harsh environments such as humidity, dust, acid and alkali media, high and low temperatures, and avoid leakage caused by aging and damage of seals. The sealing leakage rate is ≤0.001%, which far exceeds the industry allowable standard.
• Product weight: The total weight is 0.8±0.05kg (standard weight, conforming to original factory specifications, moderate size, convenient for bulk storage, installation and carrying).
• Service life: Under normal working conditions, the overall service life is ≥6000 hours, the wear resistance of the seals is ≥500 times, and the sealing performance retention rate of the gasket is ≥92% after 1000 hours of continuous operation under high temperature and high pressure.
