29559682 Sealing ring Allison spare parts

Allison 29559682 is a genuine Allison transmission seal, precisely compatible with Allison 1000/2000/3000/4000 series heavy-duty automatic transmissions. It is also compatible with the sealing interfaces of transmissions from brands such as Mercedes-Benz, DAF, and Peterbilt. As a core sealing component of the transmission’s hydraulic system and component interfaces, its primary function is to seal the oil, block dust and moisture, and prevent oil leakage, impurities from causing valve core jamming, component corrosion, signal distortion, and other malfunctions. Widely used in heavy-duty scenarios such as long-haul freight, mining operations, urban public transportation, and construction projects, it boasts strong adaptability and a tight seal, making it the preferred replacement for genuine Allison maintenance and repair. It perfectly meets the sealing interface requirements of various heavy-duty transmissions, showcasing the high-quality advantages of Allison genuine parts.

Core technical parameters

-Model: 29559682
– Operating temperature: -60°C to +200°C
– Sealing performance: Static seal working pressure can reach 40MPa (without retaining ring), dynamic seal (reciprocating motion) can reach 30MPa (with retaining ring), and rotary motion dynamic seal can reach 15MPa (with retaining ring).
– Product weight: 0.04kg
– Compatible Systems: Allison 1000/2000/3000/4000 series heavy-duty automatic transmissions, and also compatible with various sealing points such as hydraulic interfaces, valve core interfaces, and housing interfaces of transmissions from brands such as Mercedes-Benz, DAF, and Peterbilt. It is suitable for high-pressure sealing scenarios in transmissions and can meet various sealing requirements such as reciprocating motion and rotary motion.
– Product type: Star-shaped sealing ring (cross-section with a four-star structure)
– Core material: Made of high-quality fluororubber (FKM/VITON)
– Product dimensions: Fully matches the original factory seal specifications, with inner diameter and cross-sectional dimensions as the core parameters, precisely fitting the dimensions of the gearbox sealing grooves without deviation.

Product Advantages

1. Original factory fit, wide compatibility: 100% matched to Allison transmission original factory specifications, with precise correspondence in size and sealing parameters. Designed according to AS568A standard, the groove is interchangeable with standard O-rings, allowing direct replacement of old parts without modification of the sealing groove or installation structure. It can also be used to replace corresponding sealing rings at sealing points of multiple brands and related transmission models. Its compatibility covers multiple scenarios such as commercial vehicles and construction machinery, and its compatibility is superior to ordinary universal sealing rings.
2. Precision sealing and accurate protection: Made of high-quality fluororubber material and precision molding process, the star-shaped cross-section design has outstanding advantages. The sealing lip is smooth and flat, fits tightly, meets the sealing pressure standard, and has extremely low leakage. It can effectively prevent oil leakage, water vapor and dust intrusion; the pre-compression is small and the friction is low, and it is not easy to twist during reciprocating motion. It has excellent starting performance and provides all-round sealing protection for the precision components inside the gearbox, which meets the high-pressure sealing requirements of heavy gearboxes.
3. Durable, stable and reliable: The fluororubber material is oil-resistant, high-temperature resistant, corrosion-resistant, and anti-aging. It has a wide temperature range and has been verified under heavy-duty cyclic conditions. It has a long service life and can effectively extend the replacement cycle of the sealing ring, reducing equipment maintenance costs. It is suitable for heavy-duty and high-frequency use scenarios such as mining and long-distance freight. Even in complex temperature and media environments, it can maintain stable sealing performance for a long time and avoid gearbox failure caused by seal failure.
