FSS ProGuard CPVC is a unique proprietary formulation of corrosion inhibitors that provide maximum protection of hard to reach areas in Steel and PVC mixed systems. This highly inhibited technology allows for long term superior corrosion protection of air gap areas that are typically found in wet and dry fire sprinkler systems that are constructed with CPVC. This product when placed in a hydrostatic enviroment provides unsurpassed corrosion protection in water, air interface and above all liquid levels. Complicated valves and the interior surfaces of piping and sprinkler components, which are often difficult or impossible to reach, are protected with this corrosion inhibitor. This product is non-flammable, low odor, bio-degradable and is specifically formulated for use in a wide temperture range and is low foaming at room temperture and typical use concentrations.
