For complete corrosion protection of water utility systems, use Advance Products & Systems’ Kleerband® Flange Protectors and Radolid® Protection caps to protect bolts, nuts and flange faces on raised face or full face flanges in areas that are subject to the ravages of extreme corrosion conditions such as wet wells, pump stations, regulator vaults, and above and below ground installations. Kleerband® Flange Protector are used for preventing corrosion from developing between flanges on piping systems. With the patented Kleerband® design, visual inspection of the flange surface can be accomplished without removing the flange protector. Kleerband® is a transparent polymer band with grease injection fittings and relief vent plug that allows 360° of continuous inspection. All sizes available. Radolid® Protection Caps with Volatile Corrosion Inhibitors (VCI) protects nuts and bolts from destructive corrosion. VCI’s are a class of colorless vapor corrosion inhibiting compounds that block the corrosive effects of electrolytes. The caps are easily pressed onto nuts and bolts by hand, snapping into place when in position. Radolid® bolt protection caps with Volatile Corrosion Inhibitors (VCI) are the best combination to prevent corrosion on different types and sizes of bolts and nuts. Available in sizes 1/4” to 3 3/4”.
