Hydra-Zorb’s Klo-Shure insulation couplings are available for metric-sized polypropylene pipe systems, including Aquatherm Blue Pipe and Green Pipe. The product creates a vapor barrier at the clamping points on insulated tube/pipe runs. It allows for sections of insulation to be secured without having to remove the clamp assembly, while also maintaining the integrity of the insulation. It is UL 25/50 flame- and smoke-rated, and made in the United States.
