This connector is suitable for the inlet to the Sequence Strainer Pot. The 2" male screw thread screws directly into the strainer pot inlet. This provides a 2" female solvent weld connection, which can accept your filter system pipework. Unlike other connectors, the Sequence Strainer Basket Quick Inlet Coupling connector has a screw thread connection in the middle. So once connected, the strainer can be disconnected from the pipework, without having to saw through your pipework.
