To make integration with non-fusible system components easier, Aquatherm offers a wide range of threaded transitions. These transitions consist of a PP-R base that has been mold-injected around a machined brass or stainless steel thread for maximum strength. These fittings are available in male and female thread types. They can include a hex head for ease of installation. Installation instructions can be found in the Aquatherm Installer Manual. The standard industrial brass fittings are manufactured with marinegrade DZR brass and are acceptable for a wide variety of uses. The lead-free fittings are compliant with the new Reduction of Lead in Drinking Water Act and are recommended for areas specifically requiring 0.25% lead content or less. Stainless steel fittings are made from Type 316 stainless steel, and are recommended for all chemically sensitive applications.
