29552485 Gasket Allison spare parts

Allison 29552485 gaskets, as original equipment manufacturer (OEM) sealing components for Allison transmissions, are designed to address the core needs of oil sealing and leak prevention at various mating surfaces in transmissions. They are widely used in the sealing components of the transmission systems of Allison’s full range of heavy-duty automatic transmissions, as well as various heavy-duty commercial vehicles and engineering/mining machinery. The products strictly adhere to OEM production standards, with comprehensive quality control throughout the entire process, from flexible graphite raw material selection, precision cutting of stainless steel core plates, composite pressing, precision stamping, and edge trimming, to sealing performance testing, temperature and pressure resistance testing, and oil resistance testing. This eliminates problems such as poor sealing, oil leakage, and gasket deformation caused by inferior materials, dimensional deviations, or insufficient stamping precision. They effectively prevent transmission oil leakage, protect the precision components inside the transmission from contamination, and are suitable for complex operating conditions such as heavy loads, high-frequency start-stop, severe vibration, and temperatures ranging from -40℃ to 180℃. They meet the processing and quality standards of GB/T 19066.3-2017, GB/T 11822-2019, ISO 9001, and CE.
