Drain & Fill Connector

Overview:

We recommend that the suction side have a different size connector than the pressure side. This ensures that the two never get connected incorrectly. Place the larger connector on the drain (suction) side and the smaller on the fill (pressure) side.

Example:

  • Filter Cart: 1″ ISO-B coupler on suction side, 3/4″ ISO-B coupler on pressure side

Please remember to select the same connector type and sizes when ordering the mating adapter kits.
