A seed cart coupler system for providing efficient connection of airseeder hoses between a seed cart and air seeder with a corrosion resistantcoupler.The seed cart coupler system generally includes a first connector adapted toberemovably connected to a second connector. The first connector includes apluralityof tubes that fluidly connect to corresponding seed hoses of a seed cart andthesecond connector includes a plurality of tubes that fluidly connect tocorrespondingseed hoses of an air seeder. The first connector and the second connectorfluidlyconnect the seed tubes of the seed cart and the air seeder when connectedtogether. The first connector and the second connector are preferablyconstructedof a material that is not corroded by fertilizer.
