Aquatherm’s line of threaded transitions use stainless-steel inserts and have been introduced to maintain the integrity of Aquatherm systems in areas with hard or aggressive water. Aquatherm’s Greenpipe, Climatherm and Lilac polypropylene-random piping systems use a simple heat fusion connection that removes toxic materials, glues and resins and open flames from the piping installation equation. The pipe and desired fitting are simply inserted onto an Aquatherm welding device and heated for a specified time and then joined together creating a single, homogenous bond. The fittings serve as an alternative to the existing brass transition fittings (where brass is unlikely to perform satisfactorily) and are available in sizes from 1/2-inch to 1 1/2 inches. Circle 10
