All Intex products are designed to be compatible with other Intex products, either through INTEX connectors or directly. If you decide to connect a competitor product to an Intex product, we cannot guarantee its proper operation or offer any parts to connect a third-party product. Intex filters are primarily designed for Intex above-ground pools. This concept is based on the fact that the bottom of the pool and the base of the pump are at the same level. If you place the filter below or above the bottom of the pool, we cannot guarantee that it will function properly and will not, for example, over-aerate. Intex uses hoses with an internal diameter of 32 or 38 mm. We do not manufacture connectors for products of other brands.
