Oatey Co.’s new FlowGuard high-contrast one-step medium green CPVC cement features a vivid coloring designed to make it easier for professional installers to identify a proper solvent-welded CPVC connection. Contrasting sharply with the yellow color of CPVC pipe, the cement’s unique green color helps installers visually identify pipe fittings that have not been solvent- welded, which can cause damaging blowouts during system testing, Oatey explains.
