iLEC Interlocking Endcaps

The DOW FILMTEC brackish water and seawater reverse osmosis membrane elements are now available with iLEC interlocking endcaps, an innovative element coupling technology that significantly enhances the performance of RO systems.

Unlike sliding couplers, the iLEC technology achieves a direct, leak-tight connection between adjacent element permeate tubes, reducing the number of sealing surfaces to a single, axially compressed o-ring. This patented design dramatically reduces the potential for seal leakage, enabling sustained higher quality permeate throughout the life of the elements, and reduces energy-consuming flow resistance, resulting in lower operating costs.
