PAI Multi-Purpose Seal

The PAI Multi-Purpose Seal delivers consistency in sealing across various truck systems that rely on pressure integrity. It performs a quiet but necessary function in blocking fluid escape and keeping contaminants out. When assemblies call for a seal that performs under shifting loads and fluid exposures, the PAI 621230 stands up to repeated service without swelling or deforming. Especially valued in drivetrain or hydraulic repairs, it adapts to use cases without being overly specific.
