At NACO we have improved upon our Bolted Compression (Repair) Couplers by introducing Injection Molded Fiberglass Reinforced PVC Flange Rings.

By adding our injection molded fiberglass reinforced PVC flange rings to our existing PVC body, you have a superior product that will not pit, rust, or scale which is so common to metal compression couplers. For a totally non-corrosive unit, add our Stainless Steel bolt pack. Each unit is pre-assembled and individually boxed for your convenience.
