K Series Inline

Omnipure’s K Series filter body features a variety of Quick-Connect™ fittings, allowing for fast, simple, hassle-free installation, and replacement. These fittings are molded directly into the filter body and cap as a single unit, reducing the chance for weeping or seepage. Cap and body are spin-welded together producing a smooth, consistent seal without the use of glues or binders that can cause contamination. The direct in-line installation eliminates the need for an additional housing. One of the primary uses of this product is as a system component. The benefit is derived from the fitting being molded directly into the filter cap, greatly reducing clearance. The K-Series filter is available in 6”, 8”, 10”, 12” or 14” lengths manufactured in 2” or 2.5” diameters and are offered with many media options including Granular Carbon, Block Carbon, Scale Inhibitor, Sediment Filtration, KDF, Nitrate Removal DI, Calcite, Softening, and more.
