29546154 Sealring,C1Piston,101.1mmID Allison spare parts

Allison 29546154 is a dedicated sealing ring for the C1 clutch piston of Allison automatic transmissions. With a precise inner diameter of 101.1mm, it is specifically designed for the hydraulic sealing of the C1 clutch piston in transmissions. It ensures the sealing and pressure stability of the clutch oil circuit, effectively preventing common faults such as transmission shifting slippage, oil pressure leakage, and weak engagement. It is a core sealing component for heavy-duty transmission repair and overhaul.
This product is made of high-performance oil-resistant fluororubber and is precision molded. It has outstanding resistance to compression deformation, high temperature and aging. It can maintain a long-term seal under continuous high temperature, high pressure and frequent operation conditions, without cracking, softening or oil leakage, ensuring the precise and reliable operation of the clutch piston.
