All Intex products are designed to be compatible with each other. If you are trying to connect an Intex pool or filter pump to another manufacturer's product, we cannot guarantee proper functionality. Intex uses a standard 32 or 38 mm diameter connection that is designed specifically for Intex products. We do not offer adapters or reducers for other sizes. We recommend that you check the connection diameters and, if necessary, consider using compatible Intex accessories.
